Abstract: A damper is provided for an airflow duct, comprising: a tubular housing, having a first end and a second end, forming a passageway through said housing along a longitudinal first axis (z), said first end further comprising a flange extending radially inward from said first end, and a damper element, linearly moveable along said first axis (z) between a first position, where said damper element sealingly engages with said flange, and a second position, where said damper element is spaced apart from and closingly oriented within said passageway in a plane substantially parallel to said flange. The damper element is pivotably movable about a central second axis (x) that is perpendicular to said first axis (z), between said second position and a third position, where said damper element is openly oriented so as to permit fluid flow through said passageway. The damper comprises an actuator, operatively coupled to said damper element, comprising an axle, arranged coaxially with and pivotably movable about said second axis (x) within said passageway, at least one first biasing member, adapted to urge said damper element towards said second position, when between said first and second position, and at least one second biasing member, adapted to urge said damper element towards said second position, when between said third and second position.
