Beschreibung
Zusammenfassung:	A seal assembly (86) for sealing a circumferential gap (11) between a first machine component (38) and a second machine component (40) which is rotatable relative to the first machine component (38) about a longitudinal axis (42). The seal assembly (86) includes a seal carrier plate (80), a primary seal (82), a mid plate (22), and at least one secondary seal (14). The seal carrier plate (80) surrounds the primary seal (82), mid plate (22), and the secondary seal (14) radially along an outer ring (50) on each axial end of the seal assembly (86). The at least one secondary seal (14) includes at least one sealing element (16). An outer radial end (92) of the primary seal (82) extends into the seal carrier plate (80) forming a mechanical fit (84). L'invention concerne un ensemble d'étanchéité (86) pour étanchéifier un espace circonférentiel (11) entre un premier composant de machine (38) et un second composant de machine (40) pouvant tourner par rapport au premier composant de machine (38) autour d'un axe longitudinal (42). Le dispositif d'étanchéité (86) comprend une plaque porte-joint (80), un joint primaire (82), une plaque médiane (22) et au moins un joint secondaire (14). La plaque porte-joint (80) entoure le joint primaire (82), la plaque médiane (22) et le joint secondaire (14) radialement le long d'une bague externe (50) à chaque extrémité axiale de l'ensemble d'étanchéité (86). Le ou les joints secondaires (14) comprennent au moins un élément d'étanchéité (16). Une extrémité radiale extérieure (92) du joint primaire (82) vient dans la plaque porte-joint (80) formant un raccord mécanique (84).
