Abstract

The control valve for a power assisted steering system has an input shaft (22) which rotates a disc (40). This disc opens or closes ports in a stationary disc (50) to control the flow of fluid from a pump to a two-way jack which provides the power assistance for the steering. The use of discs instead of pistons and sleeves reduces the length of the valve resulting in a very compact design.
