ABSTRACT:
A 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 equipped with a load responsive bypass valve or a variable displacement pump equipped with load responsive control, which during simultaneous control of multiple loads automatically maintains the pump discharge pressure at a level higher by a constant pressure differential than the pressure required by largest load being controlled. The load responsive valve is of a four position regeneration type which in the regeneration position while connecting together both of the load chambers supplies irrespective of the pressure level a constant flow into those chambers from the inlet chamber through a metering orifice.
