<p>A hydraulic rotary distributor comprising two rotary members connected respectively to an input shaft and to an output shaft for controlling the supply in pressurized fluid to a power-assistance motor as a function of their relative angular position. According to this invention, are provided locking means dependent of a control pressure for preventing said rotary members from relative rotation until the torque applied to the input shaft exceeds a predetermined value. The invention is particularly intended for use in power steering mechanisms for automotive vehicles.</p> |
