Abstract
PURPOSE: To provide a damper, wherein a blocking plate having labyrinth-shaped press fitments is pressed against a packing frame thereby complete sealing being obtained even when a small amount of dust adheres thereto.
CONSTITUTION: A damper bady 1 is provided with a packing frame having packings 3. A blocking plate 5 can seal with said packings. Labyrinth-shaped press fitments 4 are arranged. The blocking plate 5 is cuased to swing by a toggle link mechanism from a position where it is perpendicular to the direction of fluid flow to a position parallel to the first mentioned position. Thus the press fitments 4 can stick to the packings 3 to seal the flow. The seal is one direction, so that the process for sealing is easy, and further since the press fitments 4 has a laybyrinth shape, the packings 3 can be pressed and deformed to effect complete sealing even when a small amount of dust adheres thereto.
