Abstract

PURPOSE: To obtain a steering output exactly corresponding to the steering resistance with simple structure, by enabling a flow control responsing a supplied pressure of the circuit with setting area difference on pressure receiving parts in a control spool.
CONSTITUTION: Diameter of pressure receiving part 7a in rear pressure chamber of control spool 5' is constructed larger than that of pressure receiving part 6a in front pressure receiving chamber 6 to obtain pressure difference on both sides of spool. By so doing, a valve hole 4' is formed in the hole having the small 4a and large 4b sections, and the part 7a is positioned in the large section with free sliding motion. The control spool 5' moves with a corresponding the balance between the pressure working on the front and rear ends and the spring force 22, and a front pressure of restriction works on the part 6a and a rear pressure of restriction on the other part 7a. Then, until these forces regain a balance, the spool changes the position with adjusting the openning of by-pass port controlling the returning flow rate, and controls the pressure difference between the front and rear of orifice.
