ンプ。[Claims for Utility Model Registration] (1) The pressure oil in the valve chamber is sent to the gear box via the throttle passage from the supply passage communicating with the discharge side of the oil pump, and the surplus flow is sent to the oil pump through the bypass passage. In the hydraulic pump for a power steering device, the hydraulic pump is provided with a suction port configured to recirculate the oil from the reserve tank to the suction side of the oil pump, and to suck oil from the reserve tank into the bypass passage and send it to the suction side of the oil pump. A hydraulic pump for a power steering system, characterized in that a switching valve is disposed in a communication path that communicates a discharge side and a suction side of the pump, and the switching valve is operated only when the engine is started. (2) The communication path is a flow path that communicates the supply path and the suction port.Claim 1, Claim 1, Power (3-: :-!:
H″″=4616 Items 7, 4, and 7 passages are communicated with each other through the valve chamber, for a power steering device according to claim 1, which is a registered utility model. Hydraulic pump. (4) The hydraulic gimp for a power steering device according to claim 1, wherein the communication passage is a flow passage that directly communicates the supply passage and the bypass passage.
