Device for sealing between two assembly parts (1, 2) movable relative to one another, especially between two damper blades or a damper blade and a stop of a flue gas armature, containing an elastic sealing element formed by a spring-steel strip (5), which contains two flat clamping edges (6, 7) arranged next to one another in a parallel fashion and pointing to the same side and securable by means of a clamping device (9) on one side to one of the assembly parts (1 or 2), as well as sealing zone (10) curved in an arc-shaped manner, whereby the sealing element (5) rests, with a resting surface located outside of the clamping edges (6, 7), flatly on the flat supporting surface (15) of a supporting element (8), and the supporting element (8) is also securable by means of the clamping device (9) to one of the assembly parts (1 or 2), and whereby the other assembly part (2 or 1) comes into contact with the sealing element (5) in the top area of the sealing zone (10) curved in an arc-shaped manner and the relative movement between the two assembly parts (1, 2) occurs roughly tangentially relative to this top area. According to the invention, the supporting element (8) is located inside of the space enclosed by the curved sealing element (5).

Le dispositif décrit assure l'étanchéité entre deux parties (1, 2) en contact mutuel, se déplaçant l'une par rapport à l'autre, notamment entre deux ailes de clapet ou entre une aile de clapet et une butée d'un accessoire pour conduite de gaz de fumée. Le dispositif comprend un élément élastique d'étanchéité (5) constitué d'une bande d'acier à ressort et pourvu de deux bords plats parallèles adjacents (6, 7) tournés du même côté et susceptibles d'être fixés d'un côté par un dispositif de serrage (9) sur une pièce de contact (1 ou 2), ainsi qu'une zone d'étanchéité (10) en arc. En dehors des bords de serrage, l'élément d'étanchéité (5) comprend une surface d'appui qui repose à plat sur la surface plate de support (15) d'un élément de support (8) qui peut lui aussi être assujetti par le dispositif de serrage (9) à une partie de contact (1 ou 2). L'autre partie de contact (2 ou 1) entre en contact avec l'élément d'étanchéité (5) au sommet de la zone d'étanchéité recourbée en arc (10) et les deux pièces de contact (1, 2) se déplacent l'une par rapport à l'autre à peu près tangentiellement à ce sommet. L'élément de support (8) se situe dans l'espace défini par l'élément courbe d'étanchéité (5).
