The drive gear (1) rotates the driven gear (2) sothat oil is transferred from the suction to thepressure side of the pump.

The plates (3) both as bearings for the gears andbalance the axial and radial faces in proportion tothe operating pressure.

Gear motors are dimensionally the same as thecorresponding pumps and in operation providethe opposite function to the pumps.(However it is not possible to convert a pump into

a motor.)Due to the internal seal layout these motors aresingle direction rotation and cannot be driven inreverse. Internal leakage oil is fed internally tothe low pressure side.

Output torques from 115 up to 3900 Nm

Displacementsfrom 52 to 2095 cc/rev

Description

Gerotor motors are slow speed/hightorque motors.The power element of this motor is the rotor unit,comprising rotor, outer ring (stator) and7 cylinders. (BMP has 6 cylinders.)The patented rotor profile prevents direct leakagebetween the pressure chambers, resulting innegligible internal leakage and volumetricefficiency.

Description

The hydraulic oil from the inlet is fed over thedistributor plate to the pistons, which execute apower stroke. The oil pushes the pistons radiallyoutwards, so that the cam cylinders attached to

the pistons press against the cam ring which isfirmly attached to the motor housing, therebyforcing the motor housing, as well as the oildistributor, to rotate.As soon as the piston reaches the end of its powerstroke the rotating oil distributor closes the inletopening and opens the outlet. The piston is thenpushed back through the cam in the cylinder andthe oil flows away through the return piping.The change in rotational direction of the motor iscarried out by changing over the inlet flowdirection. This can also be done during operationand without stopping.

These proportional valves control the rate of flow tothe receiver irrespective of load, because there is a2-way pressure compensator integrated into eachdirectional control valve. In addition each directionalvalve contains pressure relief functions individuallyadjustable for each receiver.The valve system comprises 2 to 9 single sections,held together by tie bolts. A pump inlet section, 1 to 7direction valves and an end section form the valvebank.All proportional directional control valves have internalload signals for the accompanying 2-way pressurecompensator. The highest load pressure signal isconducted via check valves to the pump inlet section.

These monoblock construction valves control flow tothe receiver irrespective of load.All principle functions of the valve are integrated inone compact unit. They consist of the pump inletsection with pressure compensation and up to fourproportional directional control valve sections. Byusing internal pressure signals selected directionalcontrol valves proportionally control flow irrespectiveof load.All directional control valves may be operatesimultaneously, but only the flow rate of the receiverwith the highest pressure is controllable irrespectiveof load.The methods of operation available - manual,hydraulic, electric or any desired combination - andthe options with the different pump connectionsections with pressure compensation in 2- or 3-wayoperation or pressure valve - offer a wide scope ofapplications relief.

Pmax Series and brief description Symbol

Two-stage Spool ValvesThe High-Performance Spool Valve Principle. The main spool (2)contains within it a small 5 mm dia. pilot spool (3). This combination ofdirect and pilot actuation produces a self-regulating hydraulic amplifi-cation of the spool actuating force, in both the offset and recenteringdirections. The pressure existing at P is directed by the pilot spool to oneor other end of the main spool, thus producing a hydraulic force whichassists either the solenoid or return spring, as appropriate.This force amplification means that the High Performance Spool Valveis largely unaffected by Flow rate, asymmetry of flow paths, long periodsof energisation, high viscosities or very large pressure drops. It is ideallysuited to all applications which require extremely high reliability ofON- and OFF switching. Also, in many situations an High PerformanceSpool Valve can be designed in in place of a much larger valve.

Adapter- and Subplates, and Accessories. For modular stackingassemblies (horizontal or conventional vertical stacks) we offer a widerange of both industry standard components in ISO Sizes 2, 3, 5, 7 andspecial components covering the same flow ranges. On request, we cancombine these with the required valves to build complete, compact,functioning assemblies.

These are some examples of our very widerange of directional valve variants, many ofwhich were designed for specific customerrequirements.

SNSA are counterbalance valves actingin A, B or A and B. They ensure controlledlowering of negative loads, and leak-tightload holding. The area ratio is 4.5:1 or 3 :1.

In overload situations the valve functionsas a pressure relief valve.

SRV are direct check valves with sepa-rate slip-in, invertable, CV elements typeCRV . Bodies are available with normalP, A, B and T drillings (customer machinesstraight-through bore for C.V. sleeves) orcompletely finished for function in P or T.

Special-Purpose Valves in System Solutions


RB is a hose-burst/load lowering valvewith metering characteristics matched tothe main directional valve. It complieswith modern safetyrequirements.

FBVG a motor-mounted bidirectionalbrake valve for open loop motor drives.

REFUVA.... is a load lock valve for con-struction machinery with optimised pvalues when lifting and lowering.

Pilot Control Circuit on ConstructionMachinery

Compact, customer-specific, control blockwith integral Pressure Control Valve, 3/2spool-type Cartridge Valves, Check Valve,Accumulator and Filter. Supplies all pilot oilrequirements and controls Travel- andSlew Brakes.

2-Speed Heavy Duty Transmission con-

trolOur HBGV units have been specially desi-

gned to control 2-speed heavy duty trans-missions on construction machines. Theyare optionally available with integral pres-sure relief or pressure reducing valves inthe inlet.

The VV Stack Valve Systemfor 2/2, 3/2, 4/2 and 4/3 functions- Low-cost System- Spool and Poppet valves in same stack- High flow rates; spool valves to app.

40 I/min, Poppet valves to app. 20 l/min- Pressures to 315 bar (limited by individual

valve ratings)- 3/2 poppet valves (including closed cross-

over) can be incorporated- Additional functions can be incorporated in

stack (eg. Check Valve, pressure Reducer,Flow Control)

- Slip-on coil design permits coil changeswithout loss of hydraulic fluid

- ISO Size 3 adapter plate available- Valve function can be reversed by rotating

unit by 180 about vertical axis

Flow Measurement Devices and

Electronic Amplifiers


QSB extremely compact, bi-directionalflow meters based on a patented Discprinciple. Available in HTF cartridge forms

(DC), DD and DE. On-board electronicsproduce an analogue proportional signal inthe range 6 Volt. Changes in flow rateare signalled within milli-seconds there-fore this unit is well suited to closed-loop control systems.

EQP-01 are digital display meters for theabove QSB units. The analogue input isconverted to a 3-digit LED display.

SAN-135 is a single-channel PWM DCamplifier with ramps. SAN-227 is a 2-chan-nel PWM amplifier with ramps. All modelsare designed for proportional valve control,and are supplied in Eurocard form.

PBS-3A is a compact and low-cost, singlechannel, PWM amplifier for controllingProportional Valves. A potentiometer knoband scale-plate are situated on the frontcover. Stable, robust, adjustment. Internalpot. for Imin/ Imax settings. Full scale(270) control always available.

LRS is a power-reducing DIN plug for theranges 1555V DC and 100250 V DC. Atthe moment of switch-on, the full power(max. 40 W) is applied to the valve and

shortly afterwards this is reduced to a pre-adjusted level eg. 10W. Modern electronictechniques allow this to be done without thepower-drop being dissipated as heat. Uses:power savings; limiting coil temperaturerise; permit deliberate but transient over-current condition.
