ABSTRACT:
A rotary fluid pressure device having a housing member, a manifold assembly, an internally generated rotor type gerotor set, an end plate, and a rotatably journaled torque transfer shaft interconnected with the gerotor set and extending within the housing member and manifold assembly. The gerotor set having at least an internally toothed stator member and a rotating rotor member disposed within the stator member. The rotor member having a first and second axial end surface and external teeth which interengage with the internal teeth of the stator to define a plurality of expanding and contracting volume chambers. The rotor member also having a plurality of circumferentially spaced laterally directed fluid paths fluidly connecting the manifold assembly with a plurality of circumferentially spaced radiating fluid paths which directly connect with the volume chambers. The fluid pressure device further including a plurality of coupling members for interconnecting the components.
