ABSTRACT:
An hydraulic rotary device includes a rotor which is oscillatable in a cylindrical chamber to force hydraulic fluid through a bypass conduit from one side to the other of a stator mounted in the chamber. An adjustable fluid flow restrictor is mounted in the bypass conduit and is controlled by a computer to which signals representative of the pressures on either side of the rotor and the angular position of the rotor are applied to enable adjustment and control of the speed of the rotor and/or the force required to rotate the rotor in the chamber.
