ABSTRACT:
The damper system for controlling the flow of a gaseous fluid in a duct member is disclosed in which the combination of parallel and opposed flow characteristics is utilized to produce a composite rate of flow which varies substantially linearly with the angle of rotation of the damper blades over the full opening range. A plurality of damper blades pivotally mounted in substantially louvered fashion is utilized in one embodiment in which alternate pairs of blades are rotated in opposite directions to produce alternate parallel and opposed passage flow characteristics. In addition to being linear, the alternate parallel and opposed flow characteristics of the adjacent blade systems of the damper provide an additive advantage in mixing flow from different streams each being provided with one of the dampers. This can be produced by combining the alternate swirling and sheet flow of the damper openings in a manner which produces intermeshing of the flow and complete mixing of the two streams. In another embodiment, the combination of parallel and opposed damper flow is produced by the use of fixed blade insert members disposed between pairs of damper blades which are operated in conventional parallel fashion.
