Rexroth piston pump & motor
A10VSO Side Port Series 16/18/28/45/71/100/140
Operating pressure range - inlet:
Absolute pressure at port S
Palx min ----------0.8 bar
Palx max ----------30 bar

Operating pressure range - outlet:
Pressing at port B
Nominal pressure Pn----------280 bar
Peak pressure Pmax----------350 bar
Application with intermittent operating pressures up to 315 bar at 10% duty are permissible.

Control:
-The pressure controller serves to maintain a constant pressure in a hydraulic system within the control range of the pump. The pump therefore supplies only the amount of hydraulic fluid recurred by the system. Pressure may be steplessly set aat the control valve.
-Function and equipment as for DR. A pressure relief valve can be connected to port X for remote control applications; This is not included in the items supplied with the DRG control.
-Function and equipment as for in addition to the pressure control function, the pump flow may be varied by means of a differential pressure over an arifice or valvespool, installed in the equal to the actual required flow is equal to the actual required flow by the actuator. The DFR1 - vale has no connection between X and the tank.
-In order to achieve a constant drive torque with a varying operating pressure, the swivel angle and with it the output flow of the axial piston pump is varied so that the product of flow and pressure remains constant. Constant flow control is possible below the power curve.
