Abstract

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).
