Abstract

Es wird ein Anschlußelement für eine Hochdruckleitung beschrieben, wobei die Hochdruckleitung (16) einen Innendurchmesser d hat und eine ballig oder als Außenkonus ausgebildete Dichtfläche (17) aufweist und das Anschlußelement (1) eine damit zusammenwirkende, als Innenkonus ausgebildete Dichtfläche (5) aufweist und einen größeren Querschnitt als die Hochdruckleitung (16) hat und Mittel vorgesehen sind, um Hochdruckleitung (16) und Anschlußelement (1) zur Abdichtung gegeneinander in Axialrichtung unter Spannung zu setzen. Erfindungsgemäß ist die als Innenkonus ausgebildete Dichtfläche (5) des Anschlußelements (1) an einem als Doppelkonus (4) ausgebildeten Bereich eines in den Körper (2) des Anschlußelements (1) einsetzbaren Einsatzteils (3) vorgesehen, wobei der Doppelkonus (4) des Einsatzteils (3) eine als Außenkonus ausgebildete Dichtfläche (6) aufweist, welche mit einer am Körper (2) des Anschlußelements (1) vorgesehenen, als Innenkonus ausgebildeten Dichtfläche (7) zusammenwirkt, und wobei der Doppelkonus (4) die Erweiterung vom Querschnitt der Hochdruckleitung (16) auf den Querschnitt des Anschlußelements (1) überbrückt. Vorzugsweise ist in dem größeren Querschnitt des Anschlußelements (1) ein Einbauraum (8) zur Unterbringung eines Funktionselements (9), wie eines Filterelements vorgesehen.
