Abstract

PURPOSE: To obtain stable steering sense of a power steering system by electrically detecting a vehicle speed proportional to steering resistance accurately and controlling hydraulic fluid supply amount on the basis of the electric signal to always obtain optimum steering output.
CONSTITUTION: When an automotive engine (E) 26 is driven, the exhaust oil of a hydraulic pump P is fed through an input port 8, a variable orifice 0, and an outlet port 10 to the actuator 3b of a power steering unit 2. When the exhaust oil amount increases more than predetermined value to cause the differential pressure after and before the orifice 0 to reach predetermined value, a control spool 5 moves rightwardly against a spring 22 to thereby open a bypass port 9 so as to thus return part of the oil to a tank T. A measuring rod 13 forming the orifice 0 moves leftwardly when the solenoid 30a is urged in response to the vehicle speed signal from a vehicle speed detector 25 to reduce the opening area of the orifice 0 as the vehicle speed increases
