Abstract
A power steering device including a vane type oil pump having vanes which are radially movable in slits of a rotor to supply hydraulic fluid from an oil reservoir tank to a power cylinder through a flow passage switching valve. Chambers are defined behind the valves at base ends of the slits. Hydraulic fluid having a pressure built up by the reciprocal motion of the valves in the chambers is supplied through a solenoid coil type flow control valve to hydraulic reaction force chambers of a power cylinder control valve to thereby control a force applied between input and output shafts thereof, thereby to determine the steering force required.
