Abstract

Der Steuerkörper (70) des Brennstoff einspritzventils (4) weist einen zur Gehäuseachse (8) desachsiert angebrachten Steuerdurchlass (114) auf, welcher zur Bewerkstelligung von intermittierenden Einspritzungen von einem Verschlussteil (96) mittels einer Aktuatoranordung (26) geöffnet und geschlossen werden kann. Zur Festlegung der Umf angsposition des desachsierten Steuerdurchlasses (114) wird der Steuerkörper (70) mittels eines Zentrierstiftes (124) positioniert. Der Zentrierstift (124) wird einerseits in einer Sacklochbohrung des Steuerkörpers (70) und andererseits in einer Bohrung einer Zwischenplatte (12), eines zylindrischen Elementes (13) oder einer Distanzhülse (202) geführt. Die Aktuatoranordnung (26) ist als ein elektromagnetischer Aktuator (80) ausgeführt, bei dem sich der Anschlag (98; 99) zur Begrenzung des Hubes des Pilotventilgliedes entweder als einstückiger Bestandteil der Zwischenplatte (12) oder als ein separates Werkstück als ebene Anschlagscheibe (97) ausgeführt ist. Dank der desachsierten Position der Aktuatoranordnung (26) und der Ausführung des Anschlages (98; 99) wird eine sehr kompakte Konstruktion des Brennstoffeinspritzventils erzielt. Die kompakte Konstruktion ermöglicht den Einbau einer geeigneten Speicherkammer im einstückigen Gehäusekörper (10) des Brennstoff einspritzventils oberhalb der Hochdruckzufuhrbohrung (20).
