Abstract

Liaison filetée pour le raccordement d'un tuyau sous pression, notamment un tuyau d'injection de moteur à combustion interne. La liaison comprend un élargissement du tube 1, formant une partie d'extrémité à deux surfaces coniques de sommets opposés 2, 3, d'angles au sommet gamma 1 , delta 1 , un écrou 5 à chapeau qui comporte une surface conique 6 d'angle au sommet gamma 2 laquelle coopère avec la surface conique arrière 2 de la partie d'extrémité, et une contre-pièce 7, qui se visse dans l'écrou 5, et comporte une surface conique 8 d'angle au sommet delta 2 qui coopère avec la surface conique avant 3. gamma 2 est compris entre 55 et 70 degrés et est inférieur de 1/2 à 12 degrés à gamma 1 . De préférence, ( gamma 1 - gamma 2 ) =< ( delta 2 - delta 1 ). Application au moteur à combustion interne.
