ABSTRACT:
A fuel injector, in particular for the direct injection of fuel into the combustion chamber of an internal combustion engine, includes a valve needle, which cooperates with a valve seat surface to form a sealing seat, and an armature engaging with the valve needle. The armature is arranged on the valve needle in an axially movable manner and damped by a damping element made of an elastomer. Arranged between the armature and the damping element is an intermediate ring, and the damping element rests on a flange that is connected to the valve needle by force locking. Due to the intermediate ring, the armature is supported on the valve needle in a twist-proof manner.
