Abstract
A solenoid valve for a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine having an injector body which includes an electromagnet. An armature group of the solenoid valve may be actuated by this electromagnet to relieve the pressure in a control chamber, so that a nozzle needle/tappet assembly in the injector body implements an opening/closing movement. The armature group includes a first and a second armature part. The first armature part and the second armature part are joined to one another by an insert-and-twist connection, one of the armature parts being enclosed by an armature guide which includes anti-rotation elements.
