ことを特徴とする燃料噴射ポンプ。[Claims for Utility Model Registration] A high-pressure chamber connected to a fuel suction mechanism, a distribution mechanism, and an injection amount control mechanism is formed in a rotary shaft, and a plurality of oil feeding mechanisms are located on one side of the high-pressure chamber. In an internal cam ring type fuel injection pump mounted in parallel on a rotary shaft, in the high pressure chamber. When the cam profile acceleration of the inner cam ring that the plunger follows is in the negative region, the length of the plunger layer of one of the pair of plungers configuring the oil feeding mechanism located at the closest part is set to A fuel injection pump characterized in that the plunger is formed in a length that blocks or narrows communication between the plunger pump chamber formed by the plunger pump chamber and the high pressure chamber, and is longer than the length of the other plunger.
