ことを特徴とする燃料噴射弁。 A leak passage is provided at the discharge port of the fuel injection pump to communicate with an oil reservoir chamber communicated via a high pressure oil passage to cause high pressure oil in the oil reservoir chamber to leak to the low pressure side, and a leak passage is provided in the middle of the leak passage. An on-off valve and an orifice are provided to open and close the passage, and the on-off valve opens when the engine is operated at low speed and low load, and when the engine is operated at low speed and low load.
A fuel injection valve characterized in that it is configured to be closed at times other than during low load operation.
