FUEL INJECTION VALVE

摘要

A fuel injection valve that uses a reduced number of structuring parts, in which a filter is not displaced or dislodged, and in which striking noise occurring when a vale member is seated is reduced. The fuel injection valve includes a valve body having an opening at its head, the valve member sliding in the valve body and opening and closing the opening in the valve body, an armature to which the valve member is fixed, a spring for urging the armature to the opening side, and an electromagnetic solenoid for moving the armature against urging force of the spring into the direction opposite the opening. The fuel injection valve injects fuel when an electric current is supplied to the electromagnetic solenoid to move the armature. The armature is made of a porous metal material to allow fuel supplied to the injection nozzle side to pass through the armature.
