Abstract
A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines, has a valve needle which cooperates with a valve-seat surface to form a sealing seat, and an armature which is connected to the valve needle, the armature being acted upon in the closing direction by a restoring spring and cooperating with a magnetic coil. The armature has a guide flange which is guided at an opposite surface. The guide flange does contact the opposite surface in all places, so that recesses are formed between the guide flange and the opposite surface.
