PURPOSE:To feed an operating fluid with sufficient pressure to a power assist device when the discharge pressure of a pump is reduced to decrease the energy loss of a suspension. CONSTITUTION:A variable-discharge pressure pump 16, the first feed passage 18 connecting the pump 16 and an active suspension 22, the second feed passage connecting the pump 16 and a power assist device 28, a booster device 30 provided in the middle of the second feed passage and boosting the operating fluid flowing in the passage, and a control device controlling the discharge pressure of the pump 16 and the action of the booster device 30 are provided. When the discharge pressure of the pump 16 is set low, the booster device 30 is operated, when the discharge pressure of the pump 16 is set high, the booster device 30 is not operated. |
