Patent ID: 8113177

Claim:
An electromagnetic fuel injection valve comprising: a plunger having a valve element arranged to come into contact with a valve seat at a tip end thereof; an anchor arranged for relative movement with respect to the plunger in a reciprocating direction; a stationary core having a through-hole extending through the stationary core in an axial direction of the plunger to form a first fuel passage, the stationary core and the anchor generating a magnetic attracting force between them; a coil configured to generate a magnetic flux in the magnetic circuit formed by the anchor and the stationary core by being energized; a first spring arranged to urge the plunger in a valve closing direction; and a second spring arranged to urge the anchor in a valve opening direction with an urging force smaller than that of the first spring; wherein said plunger includes a fuel path that is opened at an end portion of the plunger opposite to the valve element and extends through an axial center of the plunger to communicate with a second fuel passage formed at a downstream side of the anchor.
