ABSTRACT:
Disclosed is an electromagnetic type fuel injection valve including a stator iron core, an electromagnetic coil concentric with the stator iron core, a casing formed of a magnetizable material and accommodating therein the stator iron core and the electromagnetic coil, a moving body provided at its end with a valve body, a stopper for the moving body, a valve seat opposite to the stopper with the moving body interposed therebetween and a spring engaged with an end of the moving body for biasing the same, the moving body being adapted to reciprocate between the valve seat and the stator iron core under the magnetizing force of the electromagnetic coil and the biasing force of the spring, and having an armature adapted to be absorbed by the stator iron core and a rod contiguous with the valve body, the armature and the rod being formed of the same material so as to be integral with each other, a guide portion of the rod and a portion of the moving body adapted to abut against the stopper being subjected to a hardening treatment, and the electromagnetic absorbing force of the armature being increased by reducing the leak magnetic flux leaking through the rod.
