Abstract

A fuel injector valve for fuel injection systems of internal combustion engines has a magnetic coil, an armature to which the magnetic coil applies a force against a resetting spring in the lifting direction, and a valve needle connected to a valve closing member. The armature is able to move between a first stop connected to the valve needle and limiting the movement of the armature in the lifting direction and a second stop connected to the valve needle and limiting the movement of the armature against the lifting direction. The second stop is formed by a spring element.
