ABSTRACT:
An automatic temperature responsive damper assembly for use primarily with turbine-type attic ventilators is disclosed. A temperature sensitive power element capable of generating a force in the order of fifty pounds per square inch is positioned beneath the vane or vanes of the damper. The preferred power element is a sealed bellows unit containing the appropriate heat-expansible fluid. Expansion of the bellows with increased heat actuates a pivoted lever to cause opening and closing of the damper over a predetermined range of temperatures. Communication of the lever movement to movement of the damper vane or vanes is accomplished by providing the free end of the pivoted lever with an upwardly extending arm having a vane engaging camming surface. By shaping the camming surfaces in a sinusoidal fashion, a rapid initial opening of the damper is provided as well as protection against damage to the damper assembly should the maximum preset temperature be exceeded.
