Abstract (en)
[origin: EP0995882A2] The system to give a hydraulic adjustment to the angular setting of a shaft (1) in relation to a drive wheel, uses a wheel where the inner section (2) is divided into pockets by webs (4a-4d) and into pressure zones (7a-7d;8a-8d) at each pocket by webs or paddles (6a-6d). The rotation is applied by an increase or decrease in the pressure applied to the webs or paddles, which differ in both directions on the same running conditions of the motor.
