ことを特徴とするリリーフ弁付油圧ポンプ。[Scope of Claim for Utility Model Registration] When the pressure in the discharge passage of a hydraulic pump that sucks hydraulic oil through the suction passage and discharges it from the discharge passage exceeds a set pressure corresponding to a preset biasing force of a spring. In the hydraulic pump with a relief valve, the valve body receiving the applied force of the pressure slides against the biasing force of the spring and communicates the suction passage and the discharge passage. A hydraulic pump with a relief valve, characterized in that a regulating member is provided for regulating the movement at a position where a predetermined minimum discharge characteristic from the discharge passage can be ensured after the suction passage and the discharge passage communicate with each other. .
