Abstract

Für eine Hochdruck-Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine, insbesondere Otto-Motor, die Einspritzdüsen für eine Benzin-Direkteinspritzung umfaßt sowie eine diesen Einspritzdüsen vorgeschalteten Kraftstoff-Hochdruckspeicher (common rail) wird zur Erzielung einer im Aufbau einfachen und leicht montierbaren Einspritzvorrichtung vorgeschlagen, daß der Hochdruckspeicher mit lösbar gehaltenen Einspritzdüsen eine Montageeinheit bildet und diese in Montagerichtung der Einspritzdüsen am Maschinengehäuse lösbar festgelegt ist, wobei zwischen den im Maschinengehäuse auf Anschlag angeordneten Einspritzdüsen und den sie über Steckverbindungen aufnehmenden Anschlußstutzen des Hochdruckspeichers jeweils ein kraftübertragend angeordnetes Federelement vorgespannt angeordnet ist.
