Abstract
A fuel injector for fuel injection systems of internal combustion engines, having a valve needle which works together with a valve seat face to form a sealing seat, has an armature acting on the valve needle. The armature is movably guided on the valve needle and is damped by an elastomer ring made of an elastomer. The armature has at least one fuel channel for supplying fuel to the sealing seat. A flat supporting ring which axially supports the elastomer ring in the area of the outlet end of the fuel channel is arranged between the elastomer ring and the armature.
