Abstract
Raccord de tuyauterie du type à bague à sertir et à serrage par écrou ou vis. Une pièce unique de réduction à géométrie de révolution 3, 4, 5 est interposée entre le tube 6 et le corps 1, d'une part, et l'organe de vissage 2, d'autre part; cette pièce présente deux zones annulaires affaiblies 3f, 5f auto-cisaillables par compression axiale; chaque zone 3f, 5f délimite, d'une part, une lèvre de sertissage 4d, 4e et, d'autre part, une paroi conique 3b, 5b destinée à coopérer avec ladite levre de sertissage pour engager cette dernière dans le tube à raccorder 6; de part et d'autre de ces zones affaiblies, se trouve une face de butée 3e, 5e susceptible de coopérer avec une face de butée correspondante 1a, 2a, respectivement, du corps 1 et de l'organe de vissage 2. L'invention s'applique notamment aux raccords du type à compression.
