ABSTRACT:
A hydraulic machine having a continuously variable displacement includes a vane rotor having a plurality of radial vanes thereon and a connection for a torque transmitting shaft driven by a prime mover such as an engine or an electric motor. A cam ring is supported in a position surrounding the vane rotor and has an interior surface facing the vane rotor. The interior surface and the vane rotor define between them a working volume swept by the vanes. The cam ring has flexible portions therearound capable of flexing radially when inwardly directed radial forces are exerted thereon to change the shape of the swept volume within the cam ring. A control mechanism in the housing has an adjustable force generating device bearing against a force exerting member engaged with the cam ring for exerting a squeezing force on the ring to distort the cross-sectional shape of the cam ring and the swept volume within the cam ring. The adjustable force generating device includes a rod having a wedge-shaped notch therein, and the force exerting member includes a toggle having one end fitted into the notch and an opposite end engaged in a wedge shaped notch in an abutment on the cam ring. The cross-sectional shape of the cam ring swept by the vanes may be continuously adjusted by the control mechanism thereby continuously adjusting the displacement of the vane rotor per revolution thereof.
