、このプランジヤの外側にプランジヤとほぼ同心
状に配置されたスプリングによつて下死点に接近
する方向へ弾性付勢されるとともに、カム機構に
より上記スプリングの弾性に抗してその軸心方向
に往復動せしめられるようにされた燃料噴射ポン
プにおいて、径を異にする上記スプリングを複数
有し、各スプリングが上記プランジヤの軸心方向
のほぼ同一位置にて同心状に並列接続されている
ことを特徴とする燃料噴射ポンプ。 A plunger for pressurizing fuel in a pressure chamber is elastically biased in a direction approaching the bottom dead center by a spring disposed on the outside of the plunger almost concentrically with the plunger, and a cam mechanism pushes the spring toward the bottom dead center. The fuel injection pump is configured to reciprocate in the axial direction of the plunger, and the fuel injection pump has a plurality of springs having different diameters, and each spring is located at approximately the same position in the axial direction of the plunger. A fuel injection pump characterized by being concentrically connected in parallel.
