アクテイブサスペンシヨン用油圧回路装置。 It incorporates a power steering device in which hydraulic oil is supplied from a reservoir tank to a control valve by a power steering pump, and an active suspension in which hydraulic pressure is supplied from a corresponding servo valve to an actuator provided corresponding to each wheel. In a vehicle, the active suspension hydraulic circuit device supplies hydraulic pressure to the servo valve, and includes a hydraulic pressure supply passage that communicates and connects the reservoir tank and the servo valve, and a hydraulic pressure supply passage provided in the middle of the hydraulic pressure supply passage. for an active suspension, comprising: a variable flow rate pump; a return passage that communicates with the servo valve and the reservoir tank; and a communication passage that communicates with the return side of the control valve and the suction side of the variable flow pump. Hydraulic circuit equipment.
