PV series Variable Displacement Piston Pump Compensators Instruction : AO : Standard pressure compensator The basic function of variable displacement pump is maintains the constant working pressure of pump and adjusting the flow automatically to meet the demand of system. When the Outlet pressure P is lower than the setting pressure, the compensator starts working, port A connects to pump case and reset the spring to keep the pump at full flow. When the pump pressure reaches the setting pressure, the compensator port P1 connects to A, it force the spool of compensator to push swash plate decrease...
