ABSTRACT:
When oil is discharged from an actuator 11i for lowering a vehicle height, an actuator pressure Pa is higher than a pump pressure Pp so that a differential pressure valve 41 slides its valving element 42 to the left by a pressure difference. A valving element seal portion 42b, abutted against a seat face 43a closing an opening of a lower return conduit 40b, moves from seat face 43a and open to lower return conduit 40b. As a result, the closure of the connected portion in the lower return conduit 40b is opened. Thus, the passage of a return conduit 40 is opened. Then, the oil from the actuator 11i is discharged via the return conduit 40 to the reserve tank 16 while receiving less flow resistance by avoiding a passage through any solenoid valve.
