て燃料が噴射されるものである。 When the coil 15 is energized through the lead wire, a magnetic flux is generated around the coil 15 as described above.
As a result, the armature 4 is attracted to the stator 3, the valve stem 6 moves upward against the spring 9, and the valve head 8 seats on the valve seat body 7, cutting off the flow of fuel. In this case, if the slits 16 were not formed in the stator 3 as in the conventional example shown in FIG. 10, the magnetic flux would generate eddy currents flowing in the circumferential direction of the stator 3, weakening the magnetic force. In this invention, the stator 3
Since the slit 16 is formed in the slit 16, the generation of eddy currents is prevented and the generated magnetic force can be kept high. When the current to the coil 15 is cut off, the armature 4 and the valve stem 6 are moved downward by the spring 9, the valve head 8 is separated from the valve seat body 7, and fuel is injected.
