料噴射ポンプ。 It consists of a plunger barrel with a fuel supply/discharge hole drilled therein, and a plunger provided with a lead for setting an injection amount and fitted into the plunger barrel so as to be able to move forward and backward, and the end face of the plunger and the inside of the plunger barrel In a fuel injection pump, the fuel in a pump chamber defined by a circumferential surface is pumped by the plunger, and the pressure feeding of the fuel is ended by communicating the lead of the plunger with the fuel supply/discharge hole, At least one of the cut surface of the lead of the plunger and the wall surface of the supply/discharge hole of the plunger barrel is set at a predetermined angle with respect to the axial direction of the plunger, so that when the lead communicates with the fuel supply/discharge hole, the fuel flows into the fuel supply/discharge hole. A fuel injection pump characterized in that the pump contacts the wall surface of a fuel supply/discharge hole.
