Abstract:
1. A rotary fluid pressure device comprising: a housing member defining a fluid inlet port, a fluid outlet port, a first flow passage, a second flow passage and an internal bore; a manifold assembly having a first fluid passage, a second fluid passage, and an internal bore, one side of said manifold assembly adjoining said housing member; an internally generated rotor type gerotor set having at least an internally toothed stator member; and an externally toothed rotor member, disposed within said stator member, said rotor member having an internal bore and a first and a second axial end surfaces; one of said at least one stator and said rotor members having orbital movement relative to the other said member, said rotor member having a rotational movement relative to said stator, with the internal teeth of said stator member and the external teeth of said rotor member interengaging to define a plurality of expanding and contracting volume chambers; a plurality of circumferentially spaced laterally directed fluid paths in said rotor fluidly connected with said manifold assembly first and second fluid passages, a plurality of circumferentially spaced radiating fluid paths in said rotor directly connecting respective ones of said plurality of laterally directed fluid paths in said rotor to said volume chambers, with one side of said gerotor set adjoining another side of said manifold assembly; an end plate, adjoining another side of said gerotor set; a rotatably journalled torque transfer shaft operatively interconnected to said rotor and extending from said housing member; and a plurality of coupling members for interconnecting said endplate, said gerotor set, said manifold assembly, and said housing member.
