Patent

CA 2373995

The invention pertains to a coupling for interconnecting two hollow bodies, comprising two interconnectable members, which are both provided a cylindrical wall, one of which fits into the other. The cylindrical wall of first member comprises a projection or a groove on its inner side, whereas the cylindrical wall of the second member is provided with a corresponding groove or projection, respectively, on its outer side. The said projection and/or the beginning of the groove is located at a distance from the end of the respective cylindrical wall, so that the members must be inserted into one another over a certain length before the projection arrives at the beginning of the groove, wherein the ratio of the tolerance, between the cylindrical wall of the first member and the cylindrical wall of the second member, and the said length is smaller than 0.1.

La présente invention concerne un couplage d'interconnexion de deux corps creux, comprenant deux éléments interconnectables pourvus l'un comme l'autre d'une paroi cylindrique dont l'une s'adapte à l'intérieur de l'autre. La face intérieure de paroi cylindrique du premier élément comporte une protubérance ou une rainure, la face extérieure de la paroi cylindrique du second élément étant pourvue à l'inverse d'une rainure ou d'une protubérance. Cette protubérance et/ou le début de la rainure se situent à une certaine distance de l'extrémité de la paroi cylindrique correspondante, de façon que les éléments doivent être insérés l'un dans l'autre sur une certaine longueur pour que la protubérance arrive au début de la rainure, ce qui fait que le rapport de tolérance entre la paroi cylindrique du premier élément et la paroi cylindrique du second élément et la longueur considérée est inférieur à 0,1.
