Title
(EN) ARRANGEMENT OF AN OBLIQUE-CONTACT SEAL IN A TRAPEZOIDAL GROOVE
(FR) AGENCEMENT D'UN JOINT D'ETANCHEITE A CONTACT CONIQUE DANS UNE GORGE TRAPEZOÏDALE
Abstract
(EN) The invention proposes an arrangement of a biconical annular seal (22) of couched V-section, in an annular groove (24) of trapezoidal shape, the short base (30) of the trapezium shape of which corresponds to the cylindrical bottom of the groove (24) and which is open radially towards the inside in the region of the long base (32) of the trapezium, in which arrangement the seal (22) has a radially external annular base (28) and two roughly conical annular wings (26) extending radially inwards from the base (28) the radially internal end of each wing (26) being pressed axially against an associated wall (34, 36) of the groove (24), characterized in that the seal (22) is mounted in the groove (24) in such a way that the base (28) of the seal (22) is situated radially some distance from the bottom of the annular groove (24).
(FR) L'invention propose un agencement d'un joint (22) annulaire biconique à section en forme de V couché, dans une gorge (24) annulaire à section en forme de trapèze dont la petite base (30) du trapèze correspond au fond cylindrique de la gorge (24) et qui est ouverte radialement vers 1 ' intérieur au niveau de la grande base (32) du trapèze, dans lequel le joint (22) comporte un talon (28) annulaire radialement externe et deux ailes (26) annulaires globalement coniques s 'étendant radialement vers l'intérieur depuis le talon (28) dont l'extrémité radiale interne de chaque aile (26) est en appui axial contre une paroi associée (34, 36) de la gorge (24), caractérisé en ce que le joint (22) est monté dans la gorge (24) de manière que le talon (28) du joint (22) est situé radialement à distance du fond de la gorge (24) annulaire.
