Abstract (en)

[origin: DE10124747A1] Fuel injection valve comprises a valve needle (3) and an armature (20) engaging with the valve needle and having an armature buffer surface (34) facing away from the valve seat as a first buffer surface. A counter-buffer surface (35) serves as a second buffer surface interacting with the armature buffer surface. The armature buffer surface and/or the counter-buffer surface have in a recess (36) an elastic damping element (37) protruding over the armature buffer surface/ counter-buffer surface. Preferred Features: The damping element is arranged in the counter-buffer surface. The recess is a circular groove arranged concentrically to the valve needle. The damping element is a rectangular ring or an O-ring made of an elastomer, or a spring element.
