ABSTRACT:
A damper assembly for an air passage. A damper assembly includes a disk element associated with a circular orifice of an air passage, and an actuator having an associated drive element. The disk is coupled to the drive element and a fixed reference point by a linkage so that as the actuator drive element is displaced from a first limit position to a second limit position, the disk moves between a sealing position and an open position. In the sealing position, the disk perimeter is flush against the perimeter of the orifice establishing an air-tight seal between the disk and the perimeter of the orifice. In an open position, the disk is displaced from the orifice perimeter and forms an angle with a plane defined by the orifice perimeter. An array of damper assemblies may be configured with a controller for selectively controlling the position of each actuator between the respective limit positions.
