Patent

CA 2482731

A coupling for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket and a first expanded region adjacent to the socket and a second expanded region adjacent to the first expanded region. A sealing member is positioned in the first expanded region, a retainer is positioned in the second expanded region and a support washer having transversely oriented radial and coaxial flanges is positioned adjacent to the retainer. A lip turned inwardly on the second expanded region overlaps the radial flange and captures the support washer, retainer and sealing member within the coupling. The retainer has a plurality of radial teeth angularly oriented to engage a pipe and prevent its removal from the coupling.

L'invention concerne un raccord permettant de relier des segments de conduit les uns aux autres. Ce raccord est dérivé d'un accessoire de tuyauterie standard, et présente un logement comportant un emboîtement, une première région élargie adjacente à cet emboîtement, et une seconde région élargie adjacente à la première région élargie. Un élément d'étanchéité est positionné dans la première région élargie, un élément de retenue est positionné dans la seconde région élargie, et une rondelle de support présentant des brides radiales et coaxiales orientées dans le sens transversal est positionnée de manière adjacente audit élément de retenue. Une lèvre tournée vers l'intérieur située sur la seconde région élargie chevauche la bride radiale et capture la rondelle de support, l'élément de retenue et l'élément d'étanchéité à l'intérieur dudit raccord. Ledit élément de retenue présente une pluralité de dents radiales orientées angulairement, destinées à entrer en contact avec un conduit et à empêcher son retrait dudit raccord.
