Abstract: A power steering system employs a valve which directly controls the direction of flow of steering fluid and the degree of pressure of the steering fluid. In another aspect of the present invention, a sensor is used to detect steering wheel induced torque. The sensor supplies a signal to an electrical control unit which, in turn, sends a signal to an electromagnetic device controlling a spool within a valve. In a further aspect of the present invention, a non-rotary valve controls steering fluid pressure and flow through left and right turn assist outlets. In still another aspect of the present invention, a valve employs a pair of bores within which spools are linearly movable by electromagnetic devices. In yet another aspect of the present invention, a valve is provided for controlling the magnitude and direction of steering fluid pressure and flow to a steering cylinder; the valve is not mechanically engaged with a rotating member of the steering system.
