ABSTRACT:
The invention relates to a rotary hydraulic distributor comprising a primary rotary element (3) coupled to an actuating device and connected for rotation with a valve rotor, a secondary rotary element (5) coupled to a driven device and connected for rotation with a valve stator, the valve stator and the valve rotor mutually cooperating to control a double acting servomotor of the driven device, a limited relative angular displacement being permitted between primary and secondary elements (3, 5) on either side from a central rest position, and a reaction mechanism being provided in order to bias the primary element (3) toward the central rest position. According to the invention, the reaction mechanism consists of a pair of independent substantially U-shaped pistons (7) able to tilt within respectively one bore (12) of a pair of bores symmetrically provided in secondary element (5), the legs (15) of U-shaped pistons (7) engaging and biasing opposite radial ends (4) of primary rotary element (3).
