Abstract

The invention relates to an injector for injecting fuel into a combustion chamber of an internal combustion engine, comprising an injection valve member (1) which opens or closes off at least one injection opening. The injection valve member (1) is activated by means of a magnet-actuable control valve (3). The magnet-actuated control valve (3) comprises an armature (37) which has a central bore (41) in which an armature pin (19) is held in a movable fashion. The armature (37) can move between an upper (49) and a lower (47) stop on the armature pin (19). When the control valve (3) is closed, the armature (37) is held by the spring force of a spring element (61) against its lower stop (47).
