Abstract

Ein Brennstoffeinspritzventil (1), insbesondere Einspritzventil für Brennstoffeinspritzanlagen von Brennkraftmaschinen, mit einer Ventilnadel (3), die mit einer Ventilsitzfläche (6) zu einem Dichtsitz zusammenwirkt, und mit einem an der Ventilnadel (3) angreifenden Anker (20), weist eine dem Ventilsitz abgewandte Ankeranschlagfläche (34) als eine erste Anschlagfläche auf. Eine Gegenanschlagfläche (35) dient als eine zweite Anschlagfläche, die mit der ersten Anschlagfläche zusammenwirkt. Die erste oder die zweite Anschlagfläche (34, 35) weist in einer Ausnehmung (36) ein elastisches Dämpfungselement (37, 38) auf, das über die jeweilige Anschlagfläche übersteht.
