る燃料噴射装置。 A pump chamber that pumps fuel in cooperation with a plunger that reciprocates in the axial direction, an oil supply port that supplies fuel to the pump chamber, and an oil drain port that discharges the fuel returned from the pump chamber after the pump chamber has finished pumping fuel. a fuel injection pump comprising: a fuel pipe line for guiding fuel discharged from the fuel injection pump to an injection nozzle; a switching valve that communicates with the fuel pipe line and opens the fuel pipe line to a low-pressure fuel receiver in its second position; and a pressure sensor provided at the oil drain port of the fuel injection pump or a portion of the oil drain passage adjacent to the port. A fuel injection device characterized in that the pressure sensor detects the end of pressure feeding of the fuel injection pump, and the switching valve is switched from its first position to its second position.
