ABSTRACT:
A power steering apparatus of a vehicle having a changeover valve operated in one direction or the other according to the turning of a steering shaft so that a supply oil passage connected to an operational oil pressure source is connected selectively to the left or right chamber of a power cylinder. At least one oil pressure reaction chamber is arranged externally of the changeover valve to be reduced in volume by the operation in either direction of the changeover valve to oppose such operation. A control valve connects the oil pressure reaction chamber to the supply oil passage via a second oil passage. A divergent exhaust oil passage is connected to the second oil passage via a throttle. A control member, such as an exhaust pump, is connected to the exhaust oil passage to produce oil flow therein at a flow rate related to vehicle speed, the control valve including a resilient element acting therein to normally urge the control valve to an open position, excessive oil pressure in the exhaust oil passage acting on the control valve to urge the same to closed position.
