Abstract
A flow controlling assembly configured to permit air flow between a first chamber and a second chamber. A frame member includes a damper contacting surface at least partially surrounding a frame opening configured to permit the air flow therethrough. A damper plate includes a frame contacting surface configured to contact the damper contacting surface when the damper plate is in a closed position. A hinge assembly is disposed between the frame member and the damper plate. The hinge assembly is configured to permit the damper plate to rotate on a rotational axis relative to the frame member and to permit the rotational axis to translate relative to the frame member.
