状弁5には燃料噴射を終了させるべく前記通油孔31と
連通して前記プランジャ挿入穴2内の加圧燃料をスピル
させるためのスピル孔53を前記燃料室4内に向けて開
口させたことを特徴とする燃料噴射ポンプ。A plunger insertion hole 2 is formed directly in the pump body 1 made of hard steel, and a plunger insertion hole 2 is formed directly in the middle position of the plunger insertion hole 2.
to form a fuel chamber 4, and by reciprocating the plunger 3 within the plunger insertion hole 2, fuel can be pumped. 3, the opening/closing timing of the oil passage hole 31 communicating with the top portion 3a of the plunger 3 is changed, thereby controlling the amount of fuel injected, and the plunger 3 is also displaced in the axial direction. This fuel injection pump houses an annular valve 5 which acts to control the fuel injection timing, and the plunger is inserted into the annular valve 5 in communication with the oil passage hole 31 in order to terminate fuel injection. A fuel injection pump characterized in that a spill hole 53 for spilling the pressurized fuel in the hole 2 is opened toward the inside of the fuel chamber 4.
