ABSTRACT:
A power steering device has a distribution valve inserted between a high pressure source formed by a pump and a reservoir for creating a pressure difference in a fluid motor connected to the steering linkage, in response to application of a torque to the steering shaft of the vehicle, thereby providing assistance to operation of the steering linkage. A by-pass passage connects the high pressure output from the pump with the reservoir and the cross section of the by-pass passage is controlled as a function of the pressure difference between the chambers of the fluid motor. The means for controlling the cross section of the by-pass passage comprise a slidable piston disposed substantially transverse in the path of the fluid flow. The piston comprises grooves and lands for respectively allowing and interrupting fluid flow in the by-pass passage. The axial position of the piston is a function of the pressure difference.
