Abstract
A power steering motor is operatively connectable with steerable vehicle wheels for steering the vehicle wheels. An actuatable power steering valve has a neutral position in which fluid flows through the steering valve to a fluid reservoir and an actuated position in which fluid flows through the steering valve to the steering motor. A main conduit conducts fluid from the outlet port of a pump to the steering valve. A return conduit conducts fluid from the steering valve to the reservoir when the steering valve is in its neutral position and in its actuated position. An orifice is located in the return conduit. A bypass valve bypasses fluid from the main conduit to the reservoir. The bypass valve is controlled in response to a pressure drop across the orifice located in the return conduit.
