Description

EMI1.1
<Desc/Clms Page number 2>
Querschnitt der Ringrille --5-- angepasst ist, so dass er unter elastischer Verformung in die Ringrille - eingerastet wird und dann im Passsitz in diese eingreift.
Die Dichtung weist, vom Dichtungsring --6-- ausgehend eine Dichtlippe --7u auf, die sich beim Einführen des Rohrendes --2-- in Richtung auf das Muffeninnere zu umlegt und dieses Rohrende würgend und abdichtend umschliesst. Beim Ausführungsbeispiel ist die Dicke dieser Dichtlippe --7-- kleiner als das Spiel --8-- zwischen Rohrende --2-- und Muffe --4--, so dass die Dichtlippe --7-- aussen von einem in der Rohrleitung herrschenden Überdruck beaufschlagt und dadurch fester gegen das Rohrende --2-- gedrückt werden kann.
Die Ringrille --5-- ist in einem mit der Muffe --4-- einstückigen Bereich ausgeformt. Fig. 2 zeigt, dass der Fitting-l-mit der Muffe-4-in einem Spritzgussvorgang hergestellt und dabei gleich die Ringrille --5-mit hinterschnitten verlaufenden Flanken --9, 10-- geformt wird, wobei der die Ringrille ausbildende Teil des Formkernes starr mit dem Formkern verbunden ist und unter Ausnutzung der thermoplastischen Verformbarkeit unter Aufweitung des Muffenendes herausgezogen werden kann, wobei das Muffenende dann durch das thermoplastische Rückstellungsvermögen in die ursprüngliche, dargestellte Form zurückkehrt.

Cross-section of the ring groove --5-- is adapted so that it is snapped into the ring groove under elastic deformation and then engages in a snug fit.
The seal has, starting from the sealing ring --6--, a sealing lip --7u which, when the pipe end --2-- is inserted, folds towards the inside of the socket and surrounds this pipe end in a choking and sealing manner. In the exemplary embodiment, the thickness of this sealing lip --7-- is smaller than the clearance --8-- between the pipe end --2-- and socket --4--, so that the sealing lip --7-- is on the outside of one of the Overpressure prevailing in the pipeline and thus pressed more firmly against the pipe end --2--.
The ring groove --5-- is formed in a one-piece area with the socket --4--. Fig. 2 shows that the fitting-1-with the socket-4-is produced in an injection molding process and at the same time the ring groove -5-is formed with undercut flanks -9, 10-, the part forming the ring groove of the mold core is rigidly connected to the mold core and, taking advantage of the thermoplastic deformability, can be pulled out with the expansion of the socket end, the socket end then returning to the original, illustrated shape due to the thermoplastic resilience.
