초록

This invention provides an adjustable damper having a tubular duct section defining first and second diametrically opposed openings and first and second sets of detents formed radially from the material of the duct about the respective openings to define a plurality of damper settings. The first detent set is offset angularly relative to the second detent set and a valve element is provided having a circular central portion proportioned to fit within the duct section. Diametrically opposed first and second shoulders project from the periphery of the disc...
