Abstract
A gerotor device is disclosed wherein the pressurized fluid is segregated to the area of the device near the orbiting valve by the sealing of the wobblestick drive connection to the valve. In the preferred embodiment shown this sealing is accomplished by restricting the effective size of the drive opening through the valving plate of the manifold plate to an area less than that capable of being sealed by the inside drive surface of the valve.
