射装置。 The plunger barrel into which the plunger is reciprocally fitted has an oil feed hole that communicates with the plunger barrel pressure chamber to which fuel is supplied and the injection nozzle, one end of which opens into the inner surface of the plunger barrel, and the other end of which is connected to the oil feed hole. A first water passage communicating with the hole and a second water passage whose one end opens to the inner surface of the plunger barrel are respectively formed, and the other end of the second water passage is configured to forcefully feed water to the oil supply hole. A water supply means is connected to the plunger, and the first water supply means is connected to the plunger only when the plunger is near the pumping start position.
and a third water passage whose both ends communicate with the second water passage.
