Abstract
A valve for use in an air distribution system has an inlet member for the axial flow of air therethrough along a central axis. A downstream portion of the inlet tapers outwardly in the downstream direction. Support structure is presented from which an extension projects downstream along the axis of the inlet. A damper for controlling air flow through the inlet defines an aperture penetrated by the support structure extension and a second aperture radially displaced from the first aperture. A motor is attached to the damper and is directly coupled to the support structure extension. The motor selectively positions the damper along the support structure extension between a downstream open position and an upstream closed position.
