Abstract

Am Injektor (12) ist zumindest mittelbar eine quer zu dessen Längsachse (13) verlaufende Auflagefläche (36) angeordnet, an der eine Spannpratze (40) angreift, die an der Brennkraftmaschine (11) befestigbar ist, wobei der Injektor (12) in eine Bohrung (10) der Brennkraftmaschine (11) eingesetzt ist und durch die Spannpratze (40) in Richtung seiner Längsachse (13) gegen einen Anschlag (18) an der Brennkraftmaschine (11) gehalten wird. Der Injektor (12) weist in seinem Außenmantel eine Ringnut (24) auf, in der ein elastisch aufweitbarer Stützring (26) angeordnet ist, der in radialer Richtung bezüglich der Längsachse (13) des Injektors (12) über dessen Außenmantel hinausragt. Von dessen aus der Bohrung (10) ragendem Ende her ist auf den Injektor (12) ein Auflagering (30) aufgeschoben, der über einen Teil (32) seines Umfangs offen ist, der auf dem Injektor (12) um dessen Längsachse (13) verdrehbar ist, der sich am Stützring (26) in Richtung der Längsachse (13) des Injektors (12) abstützt und an dem die Auflagefläche (36) angeordnet ist.

On the injector (12) is at least indirectly arranged transversely to the longitudinal axis (13) extending support surface (36) on which a clamping claw (40) engages, which is fastened to the internal combustion engine (11), wherein the injector (12) in a Bore (10) of the internal combustion engine (11) is inserted and held by the clamping claw (40) in the direction of its longitudinal axis (13) against a stop (18) on the internal combustion engine (11). The injector (12) has in its outer shell an annular groove (24) in which an elastically expandable support ring (26) is arranged, which protrudes in the radial direction with respect to the longitudinal axis (13) of the injector (12) via the outer jacket. From its end projecting from the bore (10), a bearing ring (30) is pushed onto the injector (12) and is open over a part (32) of its circumference which is mounted on the injector (12) about its longitudinal axis (13). is rotatable, which is supported on the support ring (26) in the direction of the longitudinal axis (13) of the injector (12) and on which the bearing surface (36) is arranged.
