なうことを特徴とする分配型燃料噴射ポンプ。A distribution type equipped with a boost compensator that drives an adjustment pin with a cam surface according to the boost pressure of the engine, and drives a tension lever via a sensor pin that comes into contact with the cam surface and follows the adjustment pin to correct the injection amount. The fuel injection pump includes: a piston that is slidably fitted into a cylinder formed on the upper part of the adjustment pin and whose rond end surface abuts the end surface of the opposite cam surface of the adjustment pin; a pump chamber of the injection pump; and the cylinder. a check valve disposed and connected between the piston head side end of the pump chamber and the check valve that opens when the fuel oil pressure in the pump chamber exceeds a predetermined pressure to supply the fuel oil in the pump chamber to the end surface of the piston head; Preparation 1: When the engine speed exceeds a correction range by the boost compensator, the piston is pressed by the fuel oil pressure in the pump chamber to further drive the adjustment pin toward the increase side to perform fuel increase correction. Distribution type fuel injection pump.
