FUEL INJECTION DEVICE

PROBLEM TO BE SOLVED: To provide a simple alternate system for an accumulator fuel injection device. SOLUTION: In an electronic type fuel injection device having an injector part, through movement of a fuel control valve by an electromagnetic solenoid against the elastic force of a compression spring, a passage for high pressure fuel is opened and through movement in a reverse direction of the fuel control valve through the elastic force of the compression spring, the passage for high pressure fuel is closed. A bolt pressed in against the elastic force of the compression spring is arranged at the injector part, and this injection device is provided with a fuel injection pump having the number of high pressure fuel discharge ports equivalent to the number of cylinders; a junction pipe to which high pressure fuel is fed from a plurality of high pressure fuel discharge ports of the fuel injection pump through a first check valve; and a pressure accumulator chamber to which high pressure fuel is fed through a second check valve from the junction pipe. The pressure accumulator chamber and the injection part are interconnected.
