ABSTRACT:
A proportional priority flow regulator valve structure comprising a cartridge-type modulated orifice valve element (MOS) in a composite multiple element valve assembly. The MOS valve operates in an hydraulic circuit to receive pressurized fluid from a source of supply and responds to variations in fluid pressure and fluid flow rates acting hydraulically on a pair of inter-dependent spring-biased spools of the valve to provide a modulated orifice for delivery of a controlled fluid flow.
