分配型燃料噴射ポンプ。[Claims for Utility Model Registration] A plunger that pressurizes fuel by being rotated by a drive shaft and reciprocated by a cam disc in contact with a roller, and a plunger spring assembly that biases the plunger toward the return side. In a fuel injection pump of the type, the plunger spring assembly has three compression springs, one of which is directly below the control sleeve and the other two are on a line equidistant from the compression spring. The control sleeve has three cut surfaces corresponding to the arrangement line of the compression springs, and the offset position of each compression spring is brought closer to the center of the plunger by the space created by the cut surfaces. A distribution type fuel injection pump featuring:
