Abstract

Für einen Einspritzinjektor von Brennkraftmaschinen wird ein die Steuerfunktionen des Vorsteuerventiles umfassender Einsatz (7) vorgesehen, der als Einbaueinheit bei schmaler radialer Führung gegenüber einem aufnehmenden Gehäuse (4) axial gegen das Gehäuse über eine Stützhülse (17) abgestützt ist, die toleranzausgleichend elastisch oder bis in den plastischen Bereich verformbar ist und über deren Werkstoffspannung die axiale Abstützkraft des Einsatzes (7) im Bereich einer Dichtgrenze gegen ein Gegenstück (5) bestimmt ist.
