ABSTRACT:
A spring loaded biasing cylinder on one side of an orbiting valve is utilized to seal the orbiting valve to the manifold structure on the opposing side of the valve to eliminate the necessity for physical seals therebetween. The center drive opening of the orbiting valve is expanded such that the center drive opening sweeps the longitudinal axis of as porting plate with a separate fluid connection through the porting plate allowing drainage of the central cavity of the gerotor device. A hole extending along the longitudinal axis of the wobble stick interconnects the central drive opening of the orbiting valve with such central cavity.
