FUEL INJECTION VALVE

摘要

The invention relates to a fuel injection valve, especially an injection valve for fuel injection systems of internal combustion engines. The inventive fuel injection valve comprises a valve needle which co-operates with a valve seat surface to form a sealing seat, and an armature (20) which is connected to the valve needle, is acted upon by a return spring in the closing direction, and co-operates with a magnet coil. Said armature comprises (20) a guiding collar (34) which is guided on an opposite surface (41). Said guiding collar (34) is not fully supported on the opposite surface, in such a way that recesses (40) are formed between the guiding collar (34) and the opposite surface (41).
