料噴射ポンプ。[Claims for Utility Model Registration] 1. A control sleeve in which a cut-off port is formed is slidably fitted onto a plunger in which a lead groove is formed, and a high pressure chamber whose volume changes according to the reciprocation of the plunger; In the fuel injection pump, communication with and cutoff from a fuel reservoir chamber in which a control sleeve is arranged is performed by opening and closing the lead groove and the cut-off port by reciprocating movement of the plunger, wherein the cut-off port is connected to the lead groove. A fuel injection pump characterized in that said plunger is formed with a relief portion that opens said cut-off port before being closed away from a lower edge of said plunger. 2. The fuel injection pump according to claim 1, wherein the relief portion is constituted by an annular groove.
