射装置。 A hydraulic piston that is integrally formed and slides on each cylinder, a plunger that sucks fuel from a fuel supply path and pressure-feeds it to a fuel injection nozzle, and a solenoid valve that is installed in the hydraulic oil supply path of the hydraulic piston and opens and closes the supply path. , when the solenoid valve is closed, fuel oil is introduced into the cylinder of the plunger until the pressure of the fuel oil balances the pressure of the spring in the cylinder of the hydraulic piston and the plunger stops, and the fuel to the cylinder of the plunger. A fuel injection device comprising a fuel supply pressure control valve provided in a supply path.
