ね力に抗してニードル弁を押上げて噴口から燃料を噴射
する燃料噴射弁において、該ニードル弁内に、該油だま
りから該噴口への燃料通路に細孔で連通ずる空間を設け
ると共に、該空間と該燃料噴射弁の燃料戻し通路との間
に、所定の設定圧以上の高燃料圧にて開弁する開閉弁を
設けたことを特徴とする燃料噴射弁。In a fuel injection valve in which the fuel supplied to the oil pool in the fuel injection valve pushes up the needle valve against the spring force of the valve spring and injects the fuel from the nozzle port, the fuel is injected from the oil pool into the needle valve. A space is provided that communicates with the fuel passage to the nozzle through a fine hole, and an on-off valve that opens at a high fuel pressure higher than a predetermined set pressure is provided between the space and the fuel return passage of the fuel injection valve. A fuel injection valve characterized by:
