ABSTRACT:
A pressure compensated load responsive flow control valve for use in a system controlling a plurality of loads. The system is powered by a single, fixed displacement pump. The flow control valve is equipped with a load responsive control, which during simultaneous control of multiple loads automatically maintains the pump discharge pressure at a level higher than the pressure required by the largest load being controlled. To obtain unidirectional flow, load sensing passages of individual valve spools are connected by check valves with the load responsive control, which is equipped with a leakage control, maintaining a relatively constant leakage from load sensing circuit, irrespective of sensing circuit pressure and permitting fast response of pressure compensated load responsive flow control valve without excessive leakage losses.
