Zusammenfassung:	The fire damper comprises a frame (10) which includes a cylindrical inner section (10a) and a flange-shaped outer section (10b) which has an inner surface and an outer surface. The fire damper further comprises a valve (20), which includes a closing cone (21) and a counter cone (22) as well as a flow duct (26) between them, and a trigger mechanism (60) with which the flow duct (26) is closed in the event of fire. The fire damper additionally comprises a first fire insulating seal (50) which is fastened within an outer section (22b) of the counter cone (22) and a second fire insulating seal (51) which is fastened on the inner surface of the outer section (10b) of the frame (10). Le registre coupe-feu comprend un châssis (10) comprenant une section interne cylindrique (10a) et une section externe en forme de bride (10b) ayant une surface interne et une surface externe. Le registre coupe-feu comprend en outre une valve (20), comprenant un cône de fermeture (21) et un contre-cône (22) ainsi qu'un conduit d'écoulement (26) situé entre eux, et un mécanisme de déclenchement (60), par le biais duquel le conduit d'écoulement (26) est fermé en cas d'incendie. Le registre coupe-feu comprend en outre un premier joint isolant contre l'incendie (50), fixé dans une section externe (22b) du contre-cône (22) et un second joint isolant contre l'incendie (51) fixé sur la surface interne de la section externe (10b) du châssis (10).
