Abstract

Eine Kraftstoff-Einspritzvorrichtung (18) umfasst ein Gehäuse (28). In diesem ist eine Gehäuseausnehmung (30) vorhanden, in welcher wiederum ein Ventilelement (48)' angeordnet ist. Diesem ist mindestens ein Kraftstoff­Austrittskanal (32) zugeordnet. Die Vorrichtung umfasst ferner ein zu dem Ventilelement (48) koaxiales Hülsenteil (34), welches auf dem Ventilelement (48) sitzt. Es wird vorgeschlagen, dass die Kraftstoff-Einspritzvorrichtung (18) Ausrichtmittel (38) umfasst, welche das Hülsenteil (34) gegenüber der Gehäuseausnehmung (30) radial ausrichten, und dass das Ventilelement (48) in dem Hülsenteil (34) geführt ist.
