Abstract

Die Erfindung bezieht sich auf eine Düsennadel 4 einer Einspritzdüse 1, die innerhalb eines Injektorgehäuses angeordnet und gegen eine Gehäuseschulter 5 über eine Feder 2 vorgespannt ist. Zwischen der Feder 2 und der Gehäuseschulter 5 ist ein Piezo-Element 7 zur Ermittlung des Düsennadel-Wegs beim Öffnen bzw. Schliessen der Düsenöffnung 3. Das Piezo-Element 7 weist hierzu zwei elektrische Anschlüsse 8.1, 8.2 im Bereich der jeweiligen Stirnseiten 7.1, 7.2 auf.
