ABSTRACT:
A split-discharge balanced dual-lobe vane-type rotary hydraulic machine that comprises a housing, a rotor mounted within the housing and having a plurality of radially extending peripheral slots, and a plurality of vanes individually slidably mounted in the rotor slots. A cam ring within the housing surrounds the rotor and has a radially inwardly directed surface forming a track for sliding engagement with the vane. Opposed symmetrical pressure cavities are formed between the cam ring surface and the rotor, and fluid inlet and outlet passages in the housing are coupled to the fluid pressure cavities. The fluid inlet and outlet passages include a fluid inlet port opening into each cavity adjacent to one circumferential edge thereof, a first fluid outlet port opening into each cavity adjacent to the opposing circumferential edge thereof, and a second fluid outlet port opening into each cavity at a position circumferentially between the inlet and first outlet ports.
