ードルと、ニードルを燃料圧力に対抗して閉弁方
向に付勢するスプリングと、ニードルのリフト時
に開口して燃料を噴射する噴口とを備えた燃料噴
射装置において、ニードルの燃料受圧部に連通し
た補償室と、この補償室に摺動自由に収装されか
つ、ニードルの開弁圧力よりも高い圧力で補償室
縮小方向に付勢されるピストンを備えたことを特
徴とする燃料噴射装置。 The nozzle holder includes a needle that is slidably housed inside the nozzle holder, a spring that biases the needle in the valve closing direction against fuel pressure, and a nozzle that opens and injects fuel when the needle is lifted. In a fuel injection device, a compensation chamber communicates with a fuel pressure receiving part of a needle, and a piston that is slidably housed in the compensation chamber and is biased in a direction to reduce the compensation chamber at a pressure higher than the valve opening pressure of the needle. A fuel injection device characterized by comprising:
