ABSTRACT:
A fuel injection valve for fuel injection systems of internal combustion engines, in particular for injecting fuel directly into a combustion chamber of an internal combustion engine, said fuel injection valve comprising a fuel inlet which is designed to allow fuel to flow into the fuel injection valve, and an actuating device which can be electrically activated and cooperates with a valve arrangement in order to discharge fuel into the combustion chamber in a directly or indirectly controlled manner via a fuel outlet the actuating device having a solenoid arrangement which is to be energized, a substantially magnetically soft magnet yoke arrangement which cooperates therewith, and a substantially magnetically soft magnet armature arrangement which cooperates therewith. The magnet yoke arrangement is constituted by at least two yoke discs. At least one of the faces of each yoke disc has at least one pole web which together with the solenoid arrangement acts upon the magnet armature arrangement. Each yoke disc is composed of at least two partial yokes which contain soft iron and at least partly surround an actuating rod which supports the magnet armature arrangement.
