The Vickers inline pump series is a family ofpositive-displacement, axial-position pumpsdesigned to operate at either fixed or variabledisplacement. Figure 1 is a cross-section ofthe typical inline pump.
As the drive shaft rotates, it causes the positions to reciprocate within the cylin-der block bores. The piston shoes are heldagainst a bearing surface by compressionforce during the discharge stroke and by the shoe hold-down plate and retainer duringthe intake stroke. The bearing surface is heldat an angle to the drive shaft axis of rotationby the yoke (Figure 2).
Intake StrokeAs each piston shoe follows the shoe bearingplate away from the valve plate, the piston is withdrawn from the cylinder block. During
this intake stroke of the piston, fluid is supplied to its cylinder block bore throughthe valve plate inlet port.
Discharge StrokeFurther rotation of the drive shaft causes the piston shoe to follow the shoe bearingplate toward the valve plate. This is the discharge stroke of the piston and fluid is expelled from its cylinder bore through the outlet port of the valve plate.
Figure 3 illustrates the manner in whichpiston stroke is controlled by the yoke angle.Displacement variations that respond to pressure changes to vary the yoke angle are described on page 14.

Drive Shaft and BearingsThe drive shaft is a simple, single-piecedesign held in accurate alignment by twoanti-friction bearings.
Bearing Size MinimizedThe shaft is supported by radial bearings ateach end. Since radial loads (due to positionforces on the cylinder block) are distributedbetween the two widely spaced shaft bear-ings (front and rear, Figure 1), bearing size is minimized, reducing friction losses. This is especially important in high-speed appli-cations where the fluid disturbance andpower loss in submerged bearings increasesappreciably with bearing rpm and time.
Self-Aligning SplineThe spline that drives the cylinder block is a major diameter fit, crowned slightly to provide cylinder block self-alignment.
Cylinder BlockOptimum hydraulic pressure balancebetween the cylinder block and the valveplate (Figure 4), ensures proper hold-down,minimizes internal friction and reducestorque losses.
No Support Bearing NeededRadial loads resulting from piston reactionsare carried to the drive shaft through thedrive spline, eliminating the need for a support bearing on the cylinder block.Consequently, losses associated with such a large bearing are eliminated, in addition,this kind of load support provides optimumalignment conditions between the cylinderblock, valve plate and drive shaft, since fewer
mating surfaces are required to establish the proper geometric relationships of thesecomponents.
The effective center of the cylinder block spline is located near the rotation planeof the piston shoes to minimize movementaction on the cylinder block.
Pistons and ShoesStress analysis methods combined with verification tests have been used to arrive at an optimum piston-cylinder block design.The Vickers design places special emphasison shoe design, since this is a critical link in the efficiency, life and reliability of theinline pump design.
Precise Pressure BalancePrecise pressure balance versus speed andload capability have been achieved withoutsacrificing efficiency and life. Thrust loads on the piston shoes are controlled by pres-sure balance to a point where the resultantloads can be adequately supported by thefluid film under their outer lands. (Figure 5).
Low Cylinder WearSince minimum piston engagement in the cylinder block bore is designed to beapproximately two diameters, reaction forcesbetween the pistons and cylinder block areminimized. This reduces bore wear so thatinternal leakage remains nearly constant with time.
YokeExtensive studies have been performed on the yoke to provide a design with an optimum deflection-to-weight relationship.The yoke pivot centerline has been posi-
tioned to allow optimum design of the actuat-ing piston and control spring (Figure 6).
Shoe Bearing PlateThe use of a shoe bearing plate allows simplified yoke design, accurate lapping of the bearing surface and optimum material selection.
Piston Shoe Hold-Down PlateDuring the inlet stroke, the piston/shoe subassembly requires force to pull it out of the cylinder block bore; this force is sup-plied by the hold-down plate. It is driven andguided by contact with the shoe necks, andis held in place axially by sliding contactwith the hold-down plate retainer (Figure 7).
Shoe Hold-Down Plate RetainerThe retainer provides positive retention of the shoe hold-down plate during the intakestroke.
This retainer is secured to the yoke by screws to ensure optimum support of theshoe hold-down plate and minimum retainerloading in the areas where shoe lift forces(intake stroke) are highest. The retainerdesign and arrangement improve the high-speed capability of the pump.
Valve PlateValve plate kidney port slots have beendesigned to provide minimum power loss and pressure pulsation throughout deliveryrange. This is accomplished by designing the valve plate porting and yoke geometry

so the piston chamber pressure is raised to system pressure before opening to the outlet port (precompression) and the piston chamber pressure is lowered to inlet pressure before opening to the inlet port(decompression).
Decompression PhaseDuring the decompression phase, the energystored in the unswept volume of fluid at system pressure is returned to the system by motoring, rather than being lost by throt-tling to inlet pressure.
Shaft SealVickers Aerospace Products has developed a shaft seal configuration especially designedfor use in all aerospace pumps. Benefits ofthis design are longer life, greater reliabilityand lower overall pump costs. This face type shaft seal (Figure 8) is not a “package”design, but is a combination of simple elements. The elements most subject to wearcan be repaired at overhaul and the sealingsurface can be lapped, providing an inex-pensive procedure for obtaining new seal performance.
Rotating Sealing ElementThe simplified seal is made of high qualitymaterial such as bearing grade bronze orcarbon. The major difference from otherseals is that the sealing element rotates with the shaft while the heavier mating ringis stationary in the housing. The seal assem-bly is driven by two tabs on the retainer that engage with the pump drive shaft. Staticsealing around the circumference of the driveshaft is accomplished with the elastomericgrommet, shown in Figure 8, which is held in contact with the shaft by a garter spring.Dynamic sealing is effected by forcing therotating element against the stationary mating ring. Constant force is provided bythe wave washer; hydrostatic balance closeto 100% assures that its operation is unaf-fected by a wide variation in case pressure.
Spring Assures ContactSince the elastomeric grommet is held incontact with both the shaft and the sealingelement by means of mechanical springs,the effectiveness of the seal does not dependon the elastic properties of the grommet.Efficient sealing is not disturbed by theeffects of either age or temperature. Also,
because of the low mass of the elementsmounted on the shaft, the seal maintains full contact, even in environments with highvibration levels.
External SealingThere are few external seals required in the standard design, and in newer designsnone are subjected to high pressure. As aresult, the pump has fewer potential externalleakage paths. The structural integrity of thesingle piece housing has been proven bycompleting a 4-Life fatigue test (approx.1,440,000 cycles). The design simplifiesmaintenance tasks, reduces pkg weight, andminimizes envelope requirements.
MaterialsMaterials are chosen for high strength,long life and optimum performance. Materialsused in the standard design include bronze,and steel for the rotating group and cast aluminum for the housing and mountingflange. The valve block may be steel, tita-nium or aluminum. High performance pumps generally use wrought or forged housing and mounting flanges.

General Application Advantages
The hydraulic pump that supplies power tomove the various loads of modern aircraftand defense vehicles is a critical component.Determining the best pump for the jobinvolves three basic considerations:
• Reliability• Performance• Economy
ReliabilityThe safety of an airplane and its occupants,or the effectiveness of a missile, depends on the proper functioning of the hydraulicsystem. Realizing that product reliability isthe most important factor to the consumer,Vickers sets this as the essential, guidingobjective in all design, manufacturing and testing operations. This objective is further supported by the Product SupportDepartment of Vickers Aerospace throughfield and overhaul work and statistical studies of pumps in use.
Engineering Cooperation with CustomersClose and active engineering cooperationwith the customer is aimed at providing the proper hydraulic circuit design necessary toobtain the most reliable pump performance.
The wide use of Vickers pumps in allkinds of military and commercial aircraft and the record these pumps have estab-lished over the past years are evidence of the emphasis Vickers places on reliability.
PerformanceCertain standards and details of performanceare required by hydraulic system designers.How well a pump meets or exceeds thesespecifications is obviously important. Vickersinline pump performance is defined in thesefive characteristics:
1) Pressure RegulationSystem pressure is automatically held withina given range for all flows from zero to fullflow. The regulation range may be chosen to best fit a particular requirement and maybe as small as 3% of related pressure.The regulation compensates for changes in load demand, temperature and variation in driving speed.
2) StabilityRecovery from step loads and load pertu-bations is rapid, and pressure overshoots are not excessive when proper circuit designis employed.
3) Temperature RangeVickers inline pumps are designed to provide
optimum performance in a Type II system asdefined by MlL-H-5440G, -65° F to +275° F;(-54° C to 135° C) fluid temperature. Specialmodifications for operation at higher temper-atures can be provided.
4) EfficiencyTypical value of overall efficiency of Vickersinline pumps at rated operating conditions is 88%. Volumetric efficiency at rated operat-ing conditions exceeds 96%. These efficien-cies are maintained near these values forlong operating durations.
5) WeightVickers inline pumps have a high power-to-weight ratio. For example, the PV3-115 pumphas a ratio of 4.5 hydraulic output horsepow-er per pound (continuous rating), that rises to 5.4 hp/lb for overspeed operation.
EconomyEconomy involves original purchase price and operating costs. Operating costs in turndepend upon overhaul time, overhaul costsand reliability or unscheduled removal rate.
LifeVickers inline pumps have demonstrated long life capability both in qualification test-ing and in service.
Nearly all models have completed thequalification requirements of MIL-P-19692.
The longtime durability has been furtherdemonstrated in a wide variety of applica-tions and in other laboratory testing. Oneexample is the extended endurance test of a PV3-115 pump, following qualification to MIL-P-19692. The pump was cycledbetween 10% and 90% flow at rated speedof 6000 rpm and at continuous Type II system temperatures. After 15,000 hours,the pump was still capable of meeting newpump performance requirements.
A pilot of performance versus time is shownin Figure 9.
Service CostThe uncomplicated design of the Vickersinline pump provides a unit that has low overhaul cost. The man-hours required for disassembly, maintenance operations,reassembly and retest are minimal. Partscosts are low and a minimum of inexpensiveoverhaul tools are needed.
ReliabilityThe low wear rates, together with the addedstructural margin provided in the design,result in the ability of Vickers inline pumps to withstand frequent off design operatingconditions of temperature, speed, pressure,etc., without noticeable damage or perform-ance deterioration.
Flexibility of InstallationAn additional consideration when choosing a hydraulic pump is flexibility of installation.Vickers inline pumps have standard mountingarrangements (QAD or bolt type) with a vari-ety of inlet and outlet configurations avail-able. The pressure control has been designedas an integral component, reducing spaceand weight. In addition, the pump design is ideally suited to manifold type inlet-outlet porting and the use of quick disconnect typemounting.
Thru-Shaft AvailableFor systems where mounting pad availabilityis at a minimum, Vickers inline pumps can be provided with a thru-shaft and special end cap. This feature allows additionalaccessories to be mounted to and driven bythe Vickers pump, reducing engine mountingpad requirements. Custom designing pro-vides the package configuration that best fits a particular application.

LifeThe life of a hydraulic pump depends to agreat extent upon the operating temperature,the drive speed, and the pressure and flowextremes to which it is subjected. In addition,cleanliness of the hydraulic fluid and suffi-cient inlet pressure are very important forassuring long life.
Normal Period of OperationThe normal period of pump operationbetween overhauls in aircraft application mayrange from 1000 to more than 15,000 hoursof actual pump running time. For applicationsinvolving operation at fluid temperaturesabove 275° F (135° C), the overhaul periodmay be shorter.
EfficiencyOverhaul efficiency varies somewhat withdrive speed and outlet pressure. This valueusually exceeds 85% and may be more than90% at rated pressure and moderate speeds.During idle, the pump provides only enoughflow to satisfy its own internal leakage. In thecase of the EDV pump, in which leakage iscirculated at low pressure instead of ratedpressure during idle periods, the power lossis further reduced.
Effects of Inlet Pressure and Temperature ExtremesInlet pressure will adversely affect effi-ciency when it drops below the critical inletpressure and causes cavitation. Extremes of temperature also will somewhat reduce efficiency. At high temperatures the fluid viscosity is lowered and leakage increases.Low temperature increases fluid viscosity and increases windage loss. However, the oil quickly warms up as the pump operates.The effect of temperature is minimal exceptat very high or very low extremes.
PressureMost Vickers pressure-compensated pumpsare designed for 3000 psi (207 bar) maxi-mum outlet pressure at zero flow and auto-matically limit the steady state pressure to this value. During transient periods, pres-sure surges may instantaneously exceed this by about one-third or less. Full flow max-imum pressures are usually 2900 psi (200bar). Higher pressure pumps, especially 4000
psi, 5000 psi and 8000 psi (276 bar, 345bar and 552 bar) are being used in anincreasing number of applications which are at the forefront of hydraulic technology.Dual range pumps provide two separatepressure ranges. (See Controls section,page 14, for description of compensators).
TemperatureTemperature limits for Type II systems perMIL-H-5440G continuous full-life operationare -65° F to +275° F; (-54° C to 135° C).Vickers standard inline units can be operatedwithin these limits.
Driving SpeedsThe driving speed recommended for a particular size pump is based on pump lifeconsiderations.
The maximum speed values shown represent an optimum compromise betweenlong pump life (lower speeds) and maximumpower output (higher speeds) and may beexceeded under certain conditions.

Transient ResponseWhen a sudden load change causes systempressure to exceed the lowest value of the pump's pressure regulation range, orwhen a sudden load change occurs whilesystem pressure is in the regulation range,the pump must rapidly adjust the output flowto meet the new load condition. This requiresthat the yoke be repositioned rapidly. Thetime elapsed during the pressure change is a measure of the dynamic response of thepump and its associated circuit and load,and depends upon the following factors:
1) The Speed at Which the Yoke Angle is ChangedThis is a characteristic of the pump. Forexample, small yoke cylinder area and highcontrol value gain contribute toward rapidyoke motion for both increasing and decreas-ing displacements.
2) Pump Driving SpeedPump speed affects time response becausethe rate of flow is proportional not only toyoke angle, but also to pump driving speed.When pump speed is high, the output flowwill be high and pressure build-up time will be short.
3) The Compliance of the Circuit Circuit compliance is determined by the volume of oil under compression, the bulkmodulus of the oil (varies with temperatureand kind of fluid), elasticity of the lines andwhether an accumulator is used. Small oilvolume, high-bulk modulus, low-expansionlines and absence of an accumulator con-
tribute to fast pump response. A given flow change will result in a rapid pressurechange, causing the pump to regulate rapidly.
4) The Nature of the LoadThe nature of the load influences how rapidlya change in load resistance or flow-control is reflected in a change in system pressure.Since changes in system pressure cause thepump to regulate, the nature of the load is a factor in the speed of pump response.In general, if the load has a high resonant frequency (low inertia, high spring rate, lowdamping), response of the pump to changesin load resistance or flow control valve set-tings will be faster than in the case of a low-frequency load system.
5) The Use of an AccumulatorAlthough the use of an accumulator decreas-es the speed of pump yoke response, thespeed of load response is the important factor. With an accumulator in the system,flow will be supplied rapidly to the load whenneeded, thereby contributing to fast loadresponse. Although the pump yoke reposi-tions more slowly because of the accumula-tor, the load does not sense the reducedyoke response since the pump's function is temporarily taken over by the accumulator.
Minimum Accumulator Size DesirableIn order to keep the accumulator size at a minimum, the pump response should be asfast as possible. The size of the accumulatordetermines the time during which it can supply a given flow at a steady pressure.If a pump requires a relatively short time
to adjust flow to a new rate, a small accumu-lator may be used or the accumulator maybe eliminated.
Inlet PressurizationWhen a pump is driven at high speed withinsufficient pressure, cavitation may resultdue to the vacuum created during the intakestroke, and its sudden collapse. Also, whenflow demand is suddenly increased, the iner-tia of the fluid in the inlet line can reduce the pressure at the pump inlet below the critical value and produce cavitation andwater hammer. This has the tendency to tearparticles of metal from the affected surfaceswith resulting erosion. The amount of inletpressurization required to prevent cavitationincreases with the pump operating speed,as shown in the chart on page 59.
The chart shows recommended inletpressure for long life when operated in MIL-H-5606 or MIL-H-83282 fluid. For operation with phosphate ester based fluids,inlet pressures higher than those shown arerecommended. Short time operation belowthe recommended values can be accommo-dated. Inlet pressure limitations of specificinstallations should be discussed with theVickers application engineer. Vickers pumpscan be supplied with various control arrange-ments, each particularly advantageous forcertain individual application requirements.The pressure regulation characteristics of apump are determined by the type of controlemployed.

Types of Controls
14
Standard TypesThe standard control types are the “flat cut-off” and “differential cut-off” compensators.
Flat Cut-Off TypeThis control provides nearly constant pres-sure through the entire flow range (Figure 10)by limiting the system pressure increase toabout 3% from full flow to zero flow. It hasthe advantages of nearly constant outputpressure, high power output, minimum sizeand weight and fast response.
DescriptionA step-by-step description will give a betterunderstanding of what happens in the controlcircuit of the flat cut-off type pump. For sim-plicity, an ideal pump is described (one thatmaintains a constant load pressure for all val-ues of flow within the capacity of the pump,except when there is insufficient load to buildup the pressure). Actually, as mentioned above,pressure rises about 3% as flow decreasesfrom maximum to zero; this is caused by leak-age from the control circuit and is important for pump stability.
Refer to Figure 11. Assume that initiallythere is no resistance to flow. This will give zero system pressure and maximum flow(yoke to maximum angle).
Increasing LoadAs the load (resistance to flow) is increased,the pressure rises and flow remains maxi-mum until the pressure reaches the pressuresetting of the compensator valve spring.(A pressure setting or rated pressure of 3000psi (207 bar) is assumed here; however thesame description of operation also applies topumps of higher rated pressures.) Therefore,
3000 psi (207 bar) system pressure is just sufficient to center the compensatorvalve spool.
Flow Proportional toCompensator Valve OpeningAs further load increase causes the systempressure to exceed 3000 psi (207 bar), thecompensator valve spool is moved downward(as shown in Figure 11) and flow from the Ps line is metered to the yoke actuating piston. This flow increases with compensatorvalve opening and therefore with systempressure increase above 3000 psi (207 bar).
Control Flow IntegratedThe yoke actuating piston integrates the control flow; thus, the velocity of the piston(and yoke) is approximately proportional to the position of the compensator valve.The rate of system flow reduction varies with pressure above compensator pressuresetting.
The yoke angle is reduced until the flow is just sufficient to give the set systempressure.
At this point the yoke is in its new position and the compensator valve spool is centered.
Decreased LoadIf the load is decreased, the system pressureis temporarily reduced and the compensatorvalve spool will be displaced upward, openingthe yoke actuating piston to case pressure.
The yoke actuating spring will cause the yoke angle to increase until the flow is justsufficient to again give the set system pres-sure. The yoke is in its new position and thecompensator valve spool is centered.
Pump Leakage Flow MaintainedIf the main line flow is completely blocked,the yoke will be moved to near center, withonly enough displacement to provide thepump leakage flow. The system pressure will be maintained and the pump will provideflow when required.
Ideal Cause Was AssumedIn the preceding explanation, it was assumedthat the pump has ideal regulation; that is,no increase in supply pressure as flowdecreased from maximum to zero. As stated,this is not obtainable in practice because ofleakage. Any leakage out of the control cir-cuit requires an opening of the compensatorvalve to replace the leakage and maintainyoke position. An increase in supply pressureis required to produce the compensator valvedisplacement. Also, since a smaller yokeangle requires higher control pressure (com-pression of the yoke spring is greater), theleakage increases which, in turn, requires a greater compensator valve displacementand, therefore, a greater increase in supplypressure. A certain amount of control circuitleakage is desirable, since it limits the gainand helps to assure stable operation.

Factors Influencing RegulationOther design constants influence the reg-ulation, but leakage is the reason that any regulation range exists. Factors tending tomake the static regulation curve more verti-cal (higher gain) include low spring rates(compensator valve and yoke), low leakage,large areas (compensator valve and yokeactuating piston) and high yoke centeringforce.
Differential Cut-Off TypeThis type of control provides a somewhatgreater proportional decrease in pressure as flow increases from zero to maximum(Figure 13). A typical pressure regulationrange is 20% of rated pressure, e.g. 600 psi(41 bar) for a 3000 psi (207 bar) setting.Advantages include proper load division in systems employing two or more pumps in parallel, minimum transient pressuresurges and a high degree of stability.
Description The following step-by-step descriptionexplains how the differential type pump oper-ates to automatically limit system pressureand to provide a proportional decrease insystem pressure from the maximum to agiven pressure, as flow increases from zero to maximum. The regulation range assumed
is 2400 to 3000 psi (165 to 207 bar).The range can be altered to obtain optimumcharacteristics for a particular application.
System Pressure Less Than 2400 psi (165 bar)Refer to Figure 12. The compensator valvespool will remain displaced upward at systempressure Ps less than 2400 psi (165 bar)due to the preload of the compensator valvespring.
With the compensator valve spool dis-placed upward, the yoke actuating piston isported to case. Therefore, the yoke actuatingspring holds the yoke at the maximum angle(maximum flow position).
System Pressure More Than 2400 psi (165 bar)As system pressure (Ps) exceeds 2400 psi(165 bar) (due to increase in load), the uppermetering orifice of the compensator valveopens and the bottom orifice closes.
Flow from the control pressure (Pc) lineenters the yoke actuating piston, compress-ing the yoke spring and decreasing the yokeangle. As the spring is compressed, the control pressure, Pc, rises.
When the increase of Pc equals the amountby which Ps exceeds 2400 psi (165 bar), thevalve will be centered to keep the yoke in itsnew position.
Flow Reduction Proportional toPs above 2400 psi (165 bar)The yoke position is proportional to yokespring compression and to the increase in Pc above case pressure. Therefore, reductionof yoke angle and flow are proportional to the increase in Ps above 2400 psi (165 bar).
Increasing System PressureFlow is reduced from maximum to zero as system pressure increases from 2400 to 3000 psi (165 to 207 bar). Therefore,when Ps is 2600 psi (179 bar), a rise of 200psi (14 bar), the flow is reduced by one-third.When Ps is 2800 psi (193 bar), a rise of 400psi (28 bar), flow is reduced by two-thirds.
Decreasing System PressureWhen Ps is between 2400 and 3000 psi(165 to 207 bar), any decrease in Ps causesthe compensator valve spool to be displacedupward and oil in the yoke actuating piston is ported to case, until Pc decreases enoughto allow the spool to return to the centeredposition again. At this point the yoke remainsin its increased-flow position. Therefore,the proportional relationship applies also toincrease of flow with respect to decrease of pressure.
SummaryIn summary, pump output flow is inverselyproportional to system pressure excessabove 2400 psi (165 bar), as the pressurevaries within the regulation range 2400 to3000 psi (165 to 207 bar). Flow is maximumfor 2400 psi (165 bar) and less. Flow is zerofor 3000 psi (207 bar), except for internalleakage flow to supply lubrication. Systempressure cannot exceed 3000 psi (207 bar)(except for small transient surges during sud-den load changes) and the pump will rapidlyprovide flow when required.

ElectricallyDepressurizedVariable Pump with Blocking ValveThis control further reduces the power losswhen the pump is on standby by reducing system pressure to a lower value – example,600 to 1000 psi (41 to 69 bar) by means of an electrical signal.
DescriptionThe solenoid valve (Figure 14) is normally de-energized. In this position the pump pressure compensator operates normally to provide full outlet pressure. The blockingvalve is maintained in the open position (as shown) for outlet pressure above e.g.400 psi (28 bar).
Energizing the solenoid will port outletpressure to a depressurizing piston thatmoves the compensator valve spool down.
This connects pump outlet pressure directlyto the yoke actuating piston. Since the con-trol pressure required to hold the yoke inzero stroke position is only that necessary to overcome the yoke springs, e.g.1000 psi(69 bar) for a 3000 psi (207 bar) pump, thepump is depressurized to a 1000 psi (69 bar)level. This results in a lower input torque tothe unit and a lower power loss.
High pressure is also ported to the spring chamber of the blocking valve whenthe solenoid is energized. This hydraulicallybalances the blocking valve piston and allowsthe spring to move the piston down to theclosed position. The pump is thereby isolatedfrom the system.
The EDV/blocking valve feature has three primary uses:1) It enables individual pumps to be taken off the line during system checkout and facil-itates troubleshooting system malfunctions.2) It enables a disabled system to be shutdown in flight to avoid additional systemdamage or to prevent loss of system fluid.
3) If the pump is depressurized during anengine start, the peak torque of the pumpduring startup is reduced. This is particularlyimportant if the pump is to be driven by anauxiliary power unit or air turbine. It may beimpossible to start the power unit or air tur-bine unless this feature (or a flow bypass) is incorporated.
EDV Used with Either Type Cut-OffAlthough Figure 14 shows a flat cut-off compensator, the EDV feature also may beused with the differential type. It has noeffect on the pump's regulation characteris-tics except when the solenoid is energized.Since the driving speed of the pump is con-tinuous and unaffected by depressurization,the outlet pressure builds up very rapidlywhen the solenoid circuit is opened.

EDV Feature without Blocking ValveIf the hydraulic system contains a checkvalve close to the pump outlet port and nor-mal system pressure is maintained duringperiods of pump depressurization, the block-ing valve may be eliminated. This results insavings of cost, envelope and weight.
Dual Range ControlThis control provides two separate outputpressure ranges (Figure 16). Selection ismade by means of an external signal (elec-trical, mechanical or hydraulic). It permits the use of smaller hydraulic components in systems that require short, high-powerdemand periods. The dual range control alsoreduces friction and leakage losses duringlow-power demand periods. Extended pumplife is still another benefit.
Preload Determines System PressureAs previously explained, the preload on the pressure compensator spring determinesthe system pressure at which the pumpbegins regulating. Compressing the spring(increasing preload) causes the pump to reg-ulate at a higher pressure, and conversely,relaxing the spring (decreasing preload) provides regulation at a lower pressure.
No Pressure at “E”As seen in Figure 15, the compensator spring is in the extended position (low pre-load) when there is no pilot pressure at “E”.This means that a relatively low system pressure is required to overcome the springpreload force and the pump will regulate at its lower range.
Pressure at “E”When pilot pressure acts at “E”, the lowerend of the spring is forced upward until astop is reached. The position of this stopdetermines the amount of additional springpreload and thus determines the systempressure at which regulation in the higherrange occurs. The pressure at “E” must besufficient to hold the piston firmly against thestop. This pressure can be provided from anexternal source, or it can be supplied fromthe pump output through a solenoid-con-trolled valve.

Constant HorsepowerControlThis control limits power output to a givenvalue for a given pump speed and maintainsit at a nearly constant level within a givenflow range (Figure 18). It has the advantage of keeping pump power source requirementsat a minimum.
The purpose of the constant horse-power is to limit the maximum pump power by beginning flow reduction at a given inter-mediate system pressure (point A) and tocause the pump to reach near rated pressureat a given intermediate flow (point B).
Yoke Spring PreloadedRefer to Figure 17, System pressure, Ps actsat all times on area “H”. The yoke spring is preloaded with a force equal to area “H” multiplied by the pressure at which it is desired to have flow reduction begin (referto point A in Figure 18). As system pressurereaches this value, the preload is overcomeand further pressure increase will produce a proportional decrease in flow. The rate ofthe spring and the area “H” will determinethe slope from “A” to “B” (Figure 18)
Design Flexibility AllowedThis control allows considerable design flexibility. As system pressure reaches avalue slightly less than rated, the compen-sator valve opens, control pressure acts onarea “C”, and from point B to zero flow, thepump operates as a basic flat or differentialcut-off unit.
Provisions For SpecialRequirements1) Integral Boost StageIf your application requires the pump to oper-ate at unusually low inlet pressure, a booststage can be added. This is a centrifugalpump that permits operation at inlet pressurewell below atmospheric. A typical applicationis an aircraft main engine pump with a mini-mum inlet requirement of five psia.
The impeller adds to the length andweight of the pump, but results in overallsystem weight reduction and increased reliability in applications where inlet pressuremay be quite low.
2) Startup Bypass ValveA simple, reliable, low-cost valve may be incorporated in the pump valve block to bypass flow and minimize torque duringstartup. This is sometimes important toreduce cranking torque of an engine or startup current of a motorpump. The flow isbypassed to inlet, at very low pressure, untila given flow is reached; the bypass valvethen closes and remains closed until systempressure is reduced to near zero, at whichtime it opens and is ready for the next start.Operation is completely automatic and self-contained. There are no electrical connec-tions and torque during startup is even lessthan that of the EDV feature in the depres-surized mode.
3) Pressure PulsationA pulsation damping chamber (attenuator)can be incorporated in the valve block to provide reduction of the outlet pressure ripple. This adds to the envelope and weightof the pump, but is justified for applicationswhere lower pressure pulsation levels areessential and the required compressibility is not provided by the load circuit.

Servo ControlServo Control of variable displacementpumps is defined as a control where the out-put is proportional to the input signal. Theoutput may be pressure or flow. The controlvalve usually is an electrohydraulic valve butcould be direct drive, fluid, pneumatic orother type valve.
There are two methods of servo signalcontrol for variable pumps and motors. Thefirst is used where only a variable pressuresetting is desired. This provides a variabledelivery component with a variable pressuresetting determined by the control signal.
The second method of servo control is to vary the displacement of the pump to provide flow proportional to the controlsignal. This type of control is generally usedwith a feedback network to control velocity orposition of an actuator, or speed of a rotatingdevice like a constant speed generator.
Intelligent ControlTM
Intelligent Control is a trademark for aVickers controller that can be used with vari-able pumps or motors. This controller canfurnish all the characteristics of the controls mentioned in this brochure plus additionalcontrol capability such as position control.In addition, the Intelligent Control has moreaccuracy and flexibility. One control functioncan be commanded with a single controlmodule. In addition to various control func-tions, Vickers Intelligent Control has thecapability to provide diagnostics, built in test,health monitoring and integrity testing. Thepressure and power control mode character-istics in Figure 19 show the precise controlthat is available with the Intelligent Control.The control can also be programmed to limittransient cavitation, reduce starting torquerequirements and control multiple compo-nents. The Intelligent Control has beendesigned to be central to a hydraulic energymanagement system that will minimize system heat rejection and reduce the totalsystem weight.

3000 psi (207 bar)3000 psi (207 bar) has been the most com-monly used system pressure for aerospaceapplications. Vickers has created variabledisplacement pumps to meet the full range of 3000 psi (207 bar) power applications.Virtually all Vickers pumps have been qualified and sufficient testing has been per-formed to generate the typical performancecurves shown in this section. The table to the right presents the basic characteristicsfor Vickers 3000 psi (207 bar) pumps.
4000 psi (276 bar)and HigherHigher system pressures have been selectedfor military applications and have been in use for several years. These applicationsnormally require additional Vickers engineer-ing involvement.

FOR EXAMPLEfor a PV3-075 pump, using typical efficiencies:
PerformanceCalculationsThe following efficiencies are given as aguide for obtaining preliminary flow, torqueand power performance values for ratedspeed and pressure. Since flow and torquelosses also vary with fluid temperature,type of fluid and other operating conditions,we recommend that a Vickers applicationengineer be consulted before finalizing thedesign parameters. This is especially true if outlet pressure or pump driving speed forthe application is different from rated pres-sure (3000 psi) and normal speeds listed on pages 11 and 21. The curves on pages24 through 56 give performance values formost of the models at three different speeds.
Typical performance through the pres-sure and flow range at 2/3 rated speed,full rated speed and 125% rated speed areshown (except for PV3-300 and PV3-375 for which the curves are at somewhat higherspeeds).
A generalized curve of recommendedinlet pressures for various pump speeds isincluded on page 59.
FlowTo obtain the value of pump outlet flow, calculate the theoretical value using pump equationnumber 1) from page 21, and MULTIPLY that flow by the applicable volumetric efficiency.Subtract outlet flow from theoretical flow to obtain flow loss.
Qtheo = (.75 cu in/rev) (7000) rpm) = 22.7 gpm231
Qoutlet = (22.7 gpm) (.96) = 21.8 gpm
Qloss = (22.7 - 21.8) = 0.9 gpm
(Multiplying by .96 Volumetric Efficiency)
TorqueTo obtain the value of pump input torque, calculate the theoretical value using pump equationnumber 2) from page 21, DIVIDE that torque efficiency. Subtract theoretical torque from inputtorque to obtain torque loss.
Ttheo = (.75 cu in/rev) (3000 psid) = 358 lb•in2π
Tinput = 358 lb•in = 389 lb•in.92
Tloss = 389 - 358 = 31 lb•in
(Dividing by .92 Torque Efficiency)
Shaft Input PowerShaft input power is calculated by multiplying input torque (obtained above) by shaft speed, anddividing by 63,025 (see pump equation number 3 from page 21).
HPinput = (389 lb•in) (7000 rpm) = 43.2 HP63,025
(389 ib•in is Tinput calculated above)
Hydraulic Output PowerHydraulic output power is calculated by multiplying outlet flow (obtained above) by differentialpressure, and dividing by 1714 (see pump equation 3a from page 21).
HPoutput = (21.8 gpm) (3000 psid) = 38.2 HP1714
(21.8 gpm is Qoutlet calculated above)
Power LossPower loss is obtained by subtracting the value of hydraulic output power form shaft inputpower. Power loss can also be obtained by using either of the following equations:
Power Loss = (Power Input) (1 - overall efficiency)
Power Loss = (Power Output) ( 1 -1)overall efficiency
HPloss = 43.2 - 38.2 = 5.0 HP
(also, HPloss = (43.2) (1 - .885) = 5.0 HP)
(and, HPloss = (38.2) ( 1 - 1) = 5.9 HP.885
