ABSTRACT:
Multi-functional rotary hydraulic machines and machine systems combining a common rotary drive system with a family of mechanically interchangeable rotary hydraulic machine units having different hydraulic functions.
The machines have a static outer casing mounting a prime mover. The prime mover comprises a stator assembly and a rotor assembly. The stator assembly is mounted within and encased by the static outer casing. The rotor assembly comprises a pair of half-shafts by which the rotor assembly is rotatably mounted within the stator assembly. The rotor assembly further comprises mounting and coupling means by which a selected one of a plurality of mechanically interchangeable rotary hydraulic machine units is mounted within and coupled to the rotor assembly for rotation therewith. The rotary hydraulic machine units each have a different hydraulic function. Numerous different hydraulic machine units are described.
The machine system of the invention allows a hydraulic versatility not previously possible.
