成したことを特徴とする電磁式燃料噴射弁。 a nozzle holder having a fuel port on the outer periphery;
A nozzle body having a nozzle hole at the tip that is connected and held to the tip of the nozzle holder, a needle valve that is slidably housed in the nozzle body, and a spring that biases the needle valve in the valve closing direction. An iron core placed in the center of the nozzle holder opposite to the iron piece connected to the rear end of the needle valve, and wound around a coil bobbin fitted into an annular space between the iron core and the inner peripheral surface of the nozzle holder. In an electromagnetic fuel injection valve comprising a coil and an electromagnet capable of driving the needle valve in a valve opening direction, a notch is provided in a flange at both ends of the coil bobbin that is fitted into an inner circumferential surface of the nozzle holder. An electromagnetic fuel injection valve characterized in that a fuel flow path is formed around the coil bobbin.
