Abstract
(EN)
In the present invention, a joint member (60) comprises: a joint body (61) that is provided at an end portion of a fluid channel (21, 41) and that has a male thread (62) formed therein; a nut (70) that has formed therein a female thread (73) corresponding to the male thread (62) and that has a straight section (14) of communication piping (12) inserted therethrough; and a retaining member (80) that is disposed between the joint body (61) and the nut (70) and that deforms inward in the radial direction of the nut (70) as a result of the nut (70) being fastened to the joint body (61). The nut (70) and the retaining member (80) are attached to the joint body (61) in a non-connected state in which the communication piping (12) has not been connected to the joint member (60).
(FR)
La présente invention concerne un élément joint (60) comprenant : un corps de joint (61) qui est disposé au niveau d'une partie extrémité d'un canal de fluide (21, 41) et dans lequel un filetage mâle (62) est formé ; un écrou (70) dans lequel est formé un filetage femelle (73) correspondant au filetage mâle (62), et à travers lequel une section droite (14) d'une tuyauterie de communication (12) est insérée ; et un élément de retenue (80) qui est disposé entre le corps de joint (61) et l'écrou (70) et qui se déforme vers l'intérieur dans la direction radiale de l'écrou (70) suite à la fixation de l'écrou (70) au corps de joint (61). L'écrou (70) et l'élément de retenue (80) sont fixés au corps de joint (61) dans un état non raccordé dans lequel la tuyauterie de communication (12) n'a pas été raccordée à l'élément joint (60).
