Abstract

PURPOSE: To enhance safety by interrupting the current supply to the electromagnetic fuel injection valve to prevent accidents such as fuel outflow due to thermal destruction of the valve bacause of the shortcircuit of the current path or the trouble of the electronic control unit.
CONSTITUTION: An electromatnetic fuel injection valve comprises an injection valve body 1 having a fuel inlet 5 through which the fuel, such as LPG, is porued, fuel pathes 6, 7, and a flange-shaped bobbin 8, an electromagnetic coil 9 wound around the bobbin 8, a movable core 12 opening the fuel path 6 when the coil 9 is supplied with current, a spring 13 biasing the movable core 12 in the fuel path 6 closing direction, and a nozzle 17. There is provided a temperature fuse 10 near the electromagnetic coil 9 for interrupting the current supply to the coil 9 when the temperature of the coil 9 rises extraordinarily high. The fuse 10 comprises a flexible sheet material 21, a pair of copper films 22, 23 to be attached to the material 21, and a solder material electrically inter connecting between the copper films.
