Abstract

PURPOSE: To provide a valve unit used in power steering system of vehicle, in which area of a pressure receiving surface, formed at one side of a rotary valve body where hydraulic pressure acted to oil supplying ports is acted, is made different from that at the other side of the rotary valve body where hydraulic pressure acted to cylinder port is received, whereby it is enabled to prevent self-excited vibration of the valve body which is possibly caused when turning back the steering shaft.
CONSTITUTION: When steering shaft 3 is turned, hydraulic pressure acted to valve body 6 is received at front and rear pressure receiving surfaces facing cylinder ports 18, 18, 18', 18' and at front and rear pressure receiving surfaces constituting oil supplying grooves 22, 22, 22', 22' and the valve body 6 is urged onto rear frame 10 of valve box 7 by a force correesponding to the difference of area between the front and the rear oil supplying grooves 22, 22, 22', 22'. Here, the force is relatively small so that it does not cause any trouble in turning the valve body 6. When the valve body 6 causes self-excited vibration at the time of turning back the steering shaft, high and low oscillating hydraulic pressure is acted respectively at ports 14, 14 and cylinder ports 18, 18, 18', 18', and valve body 6 is urged onto the frame 10 by a force corresponding to the area difference, so that the vibration of the valve body 6 can be attenuated effectively by the frictional force./
