Abstract

Die Erfindung betrifft eine Kraftstoffeinspritzdüse für Brennkraftmaschinen, bei der an den der Spritzseite abgewandten Ende der Ventilnadel, die in Strömungsrich­ tung öffnet, ein Dämpfungskolben angeordnet ist, der mit einer auf diesen Dämpfungskolben aufgesteckten zu diesem hin federbelasteten und mit diesem einen Dämpfungsraum begrenzenden Kappe zusammenwirkt. Auf der Ventilnadel ist kraftschlüssig durch die Schließfeder der Einspritzdüse belas­ tet ein Stützring angeordnet. In dem räumlichen Abschnitt zwischen Dämpfungsraum und Stützring ist um die Ventil­ nadel eine gehäusefeste gekapselte Induktionsspule vor­ gesehen, wobei der Stützring als Anker eines aus Induktions­ spule und mindestens einem als Joch dienenden Teil der Kapselung gebildeten Gebers dient.
