置。 A pump chamber that pumps fuel in cooperation with a plunger that reciprocates in the axial direction, a fuel 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 pumping of fuel is completed. 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 to a low-pressure fuel receiving portion at a second position; and a switching valve that connects the oil drain port of the fuel injection pump or a portion of the oil drain passage adjacent to the port with the switching valve. A pressure transmission device consisting of two pistons and a conduit connecting the two pistons is interposed between the two pistons, and a pressure transmission device is provided between the two pistons to transmit the oil to the oil drain port or the oil drain passage adjacent to the port immediately after the fuel injection pump finishes pumping. A fuel injection pump device characterized in that the switching valve is configured to be switched from its first position to its second position by exhaust oil pressure.
