ABSTRACT:
A damper assembly for controlling the flow of fluid through a passageway is disclosed. The damper assembly comprises a rectangular frame (22) adapted to be fitted in a passageway. A plurality of damper blades (24) are supported for pivotal motion in the frame (22) about spaced, parallel longitudinal axes (26) between opened and closed position. The blades (24) are operatively interconnected by a linkage mechanism (28) so as to be substantially simultaneously rotated as required. Operative means including a drive shaft (30) suitably attached to one or more of the blades (24) is provided for rotating the blades between opened and closed positions.
