摘要

The fuel injection valve (1) has a magnetic coil (2) which cooperates with an armature (7) which is acted upon by a return spring (14). An additional mass (18) is located in the recess (15) of the armature. The additional mass hits the armature with predetermined acceleration after an additional lift (h). The additional mass is acted upon by a spring (19) in the closure direction of the fuel injection valve.
