CA 2566274

A sealing member is disclosed having an outer surface that supports segments of a pipe coupling for joining pipe elements in end to end relation. The segments are supported in spaced relation to permit the pipe elements to be inserted into the coupling without disassembly. The sealing member is a flexible ring that has conical lips around its inner circumference to engage and guide the pipe elements into the coupling. A tongue extends radially inwardly between the lips, the tongue having conical shoulders which engage and guide the pipe ends. The tongue locates the coupling segments relatively to the pipe elements.

Cette invention concerne un élément d'étanchéité comportant une surface externe sur laquelle reposent des segments d'un raccord de tuyaux permettant de raccorder bout à bout des éléments de tuyaux. Ces segments sont disposés de façon qu'ils soient espacés les uns des autres afin que les éléments de tuyaux puissent être insérés dans le raccord sans être démontés. L'élément d'étanchéité est une bague souple comportant des rebords coniques autour de sa circonférence interne permettant d'emboîter et de guider les éléments de tuyaux dans le raccord. Une languette s'étend radialement vers l'intérieur entre les rebords, la languette comportant des épaulements coniques qui emboîtent et guident les extrémités des tuyaux. La languette dispose les segments de couplage par rapport aux éléments de tuyaux.
