ABSTRACT:
A flow control passage fluidly interconnects an output flow passage and a return flow passage to bypass a control valve. A control valve operation modifying variable orifice is disposed in and partly defines the flow control passage. The control valve operation modifying variable orifice is variable in flow area in response to at least one of vehicle control factors other than steering torque. A fixed flow area orifice is disposed in and partly defines the flow control passasge at a location downstream of the control valve operation modifying variable orifice. The control valve has a plurality of steering torque responsive variable orifices and bypass passage means for bypassing at least one of the steering torque responsive variable orifices. A differential pressure passage provides communication between the upstream and downstream sides of the fixed flow area orifice. An actuator is disposed in and partly defines the differential pressure passage. The actuator has a pressure movable part which is movable in response to variation of differential pressure produced by the fixed flow area orifice. The bypass passage means includes a differential pressure responsive variable orifice operatively connected to the pressure movable part of the actuator and variable in flow area in response to movement of the pressure movable part of the actuator.
