Zusammenfassung:	A damper assembly having a main body defining a continuous fluid path extending between a first opening and a second opening and a damper door rotatable within the main body to control the flow of fluid through the main body. The main body including an engagement edge extending circumferentially on an inner surface of the main body. The damper door can be rotated relative to the main body to sealingly engage an outer edge of the damper door with the engagement edge. The engagement edge of the main body can be oriented on the inner surface such that the surface area of the outer edge such that engagement of the engagement edge gradually increases as the damper door is rotated to seal the damper door to the main body.
