Title DAMPER BLADE SEAL Inventor James Allen Davis Abstract A rectangular damper blade rotates about its longitudinal center line between an open and closed position to control the airflow entering an enclosure. Two longitudinal edges of the damper blade become positioned between two inlet edges of the enclosure as the blade rotates to the closed position. The blade is associated with two longitudinal seals. One seal is attached directly to one of the blade's longitudinal edges and provides wiping contact against one of the inlet edges. The other seal is attached to the other inlet edge and provides wiping contact against the blade's other longitudinal edge. Both seals have similar cross-sections to facilitate their inter- changeability. And both seals include a flexible lip that extends upstream and perpendicular to the blade to enhance the sealing force and to minimize wiping friction. In the presence of an air pressure differential across the damper blade, the seals urge the blade to the closed position, and when closed, exert a radial sealing force generally parallel to the blade. The configuration of the seals provides a damper that is tolerant of misalignment which makes it suitable for direct drive actuation.
