Abstract
Ein Brennstoffeinspritzventil (1), insbesondere zum direkten Einspritzen von Brennstoff in einen Brennraum einer Brennkraftmaschine, mit einem piezoelektrischen, elektrostriktiven oder magnetostriktiven Aktor (2) und einem mit dem Aktor (2) in Wirkverbindung stehenden Ventilschließkörper (7), der mit einer Ventilsitzfläche (33) zu einem Dichtsitz zusammenwirkt, weist einen Koppler (4) mit einem ersten Koppler-Abschnitt (23) und einem zweiten Koppler-Abschnitt (24) auf. Die beiden Koppler-Abschnitte (23, 24) sind gegeneinander axial beweglich und stehen miteinander über ein in einem Volumen (36) befindlichen Hydraulikmedium in Wirkverbindung. Die beiden Koppler-Abschnitte (23, 24) werden durch magnetische Felder auseinander gedrückt.
