スプール型サーボ弁。[Claims for Utility Model Registration] A servo valve, a servo piston controlled by the servo valve, a plunger pump driven by the servo piston to supply fuel to a fuel injection nozzle, and controlling the discharge amount of the plunger pump. In the pressure booster plunger type fuel injection device, the servo valve is of a spool type, and the fuel supply port, which is opened and closed by the piston part of the servo valve, is controlled by the flow of fuel when the piston part opens. A spool-type servo valve, characterized in that the piston part is inclined so as to be pressed in the opening direction.
