液圧ポンプの制流弁装置。[Scope of Claim for Utility Model Registration] A flow control valve device that performs flow control by switching between suction flow and discharge flow for a hydraulic pump that generates pressure by alternately performing suction and compression, comprising: a valve box; A pump flow passage provided in the box and connected to the hydraulic pump and through which the suction flow and discharge flow flow; and a pump flow passage that is connected to the pump flow passage and is also connected to the suction port of the valve box, and is used for suction only when the suction flow flows. A suction flow passage opening that opens when the valve opens; and a discharge flow passage opening that communicates with the pump flow passage and the discharge port of the valve box and that opens when the discharge valve opens only when the discharge flow flows. A flow control valve device for a hydraulic pump, characterized in that the opening directions of the suction flow passageway and the discharge flow passageway are parallel to the flow directions of the suction flow and the discharge flow flowing through the pump flow passage.
