Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Demontage von Druckrohren an Einspritzeinheiten von Brennkraftmaschinen. Einspritzeinheiten, bei denen das Druckrohr (3) den Zylinderkopf (1) in einer Bohrung (5) durchdringt, um gegen das Einspritzelement (2) gepreßt zu werden haben den Nachteil, daß sich eine Demontage des Druckrohres (3) sehr schwierig gestalten kann, da das Druckrohr (3) nach dem Herausschrauben des Anschlußstückes (4) von außen schwer zugänglich ist. Erfindungsgemäß wird dieser Nachteil dadurch behoben, daß das Druckrohr (3) an dem, dem Anschlußstück (4) zugewandten Ende eine umlaufende Nut (7) aufweist, in welche im Einbauzustand ein U-förmiger Federbügel (6) eingreift, der wiederum über Ausnehmungen (8a,8b) im Anschlußstück (4) geschoben wird, so daß das Druckrohr (3) in axialer Richtung formschlüßig mit dem Anschlußstück (4) verbunden ist, ohne daß die Drehbarkeit des Anschlußstückes (4) behindert wird. Das Anschlußstück (4) kann also bei Demontage des Druckrohres (3) herausgeschraubt werden und das Druckrohr (3) wird gleichzeitig über den Federbügel (6) und die Nut (7) aus der Bohrung (5) herausgezogen.
