Abstract

PURPOSE: To obtain a small-sized electromagnetic fuel injection valve by providing gaps between a stator core and an armature of the injection valve and between a main body case and the armature as magnetic routes for promoting the suction force.
CONSTITUTION: A stator core 17 to be also used for a fuel pipe, an armature 21 fast fixed on a needle valve 22 in one body, and a spring 26 between the armature 21 and the stator core 17 are provided round the axis of a main body case 13 of an electromagnetic fuel injection valve 12, and besides, a solenoid coil 14 is arranged on the periphery of the core 17. A gap 27 is provided between the core 17 and the armature 21 as a magnetic route, while a gap 28 is provided between a ring-shaped wall face 25 of the case 13 and a flange face 24 of the armature 21 as another magnetic route.
