ABSTRACT:
A casing, formed to provide fluid inlet and outlet openings and a stationary internal gear intermediate the openings, the casing journaling a rotary shaft coaxial with the internal gear. Primary and secondary rotors are fixed on the shaft in axially spaced relationship, the primary rotor having fluid passages communicating with one of the openings. A fluid transfer element is fixed on the shaft between the secondary rotor and an end of the casing, and defines a fluid passage communicating with the other casing opening. The primary rotor includes a rotary internal gear disposed near the stationary internal gear. The secondary rotor has a plurality of external tooth elements, and a cooperating ring is eccentrically mounted thereon, the ring having internal tooth elements one more in number than those of the secondary rotor. The tooth elements cooperate to define inner and outer walls of successively expanding and contracting fluid chambers. An annular member is concentrically journaled on the ring and has a pair of gears thereon which mesh with the teeth of the internal gears. A pair of valve elements are disposed between opposite ends of the ring and the primary rotor and transfer element, cooperating with these to deliver fluid from one of the casing openings to the expanding chambers and from the contracting chambers to the other casing opening.
