Abstract
A vane motor is disclosed in which the volumetric displacement, torque, or speed are continuously adjustable. The vane motor includes a housing having a rotor and cam ring disposed axially around the rotor. The rotor includes vanes in radial slots which divide the motor between the rotor and cam rings. One cam ring is rotatable relative to the other so as to change volumetric displacement.
