Zusammenfassung:	The principal subject of the invention is a metallic sealing assembly (30) between a rotating shaft (16) and a fixed frame (3), characterized in that it comprises: a flexible metallic seal (1) having two tori, inner and outer, that are concentric and of different average diameters, comprising a metal envelope which encases and holds the inner and outer tori; a shaft (16) rotating about an axis of rotation (X), comprising an annular shoulder (7) against which the seal (1) comes to press; a counter-face (14), comprising a contact face (14a) against which the seal (1) comes to press; a wedge block (17) that is positioned around the rotating shaft such that the seal (1) is held between the wedge block (17) and the contact face (14a), the wedge block (17) being mounted so as to be able to slide on the rotating shaft; a metal part which forms a cap (15) through which the rotating shaft (16) passes and which is secured to the frame (3) and/or to the counter-face (14), the rotating shaft (16) being free to rotate with respect to the cap (15) and axially secured to the cap (15). L'objet principal de l'invention est un assemblage (30) d'étanchéité métallique entre un arbre tournant (16) et un bâti fixe (3), caractérisé en ce qu'il comporte: un joint d'étanchéité métallique flexible (1) à deux tores intérieur et extérieur concentriques de diamètres moyens différents, comprenant une enveloppe métallique dans laquelle sont encastrés et maintenus les tores intérieur et extérieur; un arbre tournant (16) autour d'un axe de rotation (X), comprenant un épaulement annulaire (7) contre lequel le joint (1) vient en appui; une contreface (14), comprenant une face de contact (14a) contre laquelle le joint (1) vient en appui;une cale (17), positionnée autour de l'arbre tournant telle quele joint (1) soit pris entre la cale (17),et la face de contact (14a), la cale (17) étant montée coulissante sur l'arbre tournant; une pièce métallique formant capuchon (15) traversé par l'arbre tournant (16) et fixé sur le bâti (3) et/ou sur la contreface (14), l'arbre tournant (16) étant libre en rotation par rapport au capuchon (15) et solidaire axialement avec le capuchon (15).
