| description | A power steering system includes a bypass valve assembly (34) which bypasses fluid from a main conduit (30) connected with a power steering pump (26) and motor (12). The bypass valve assembly is urged toward an open condition, bypassing fluid from the main conduit (30), with a force which varies as a function of the fluid pressure drop across an orifice (38) in the main conduit. The bypass valve assembly is urged toward a closed condition by a spring (52). In addition a pressure responsive pilot valve assembly (60) opens to communicate the fluid pressure in the main conduit to the bypass valve to urge the bypass valve assembly toward the closed condition. This decreases the rate at which fluid from the power steering pump is bypassed to thereby increase the amount of fluid available for actuation of the power steering motor. |
