Abstract (en)
[origin: EP0501073A2] A damper for controlling air flow through an air duct is provided. The damper includes a mounting frame secured to the interior of the duct which has a circular opening for air flow therethrough when the damper is open. A circular damper plate is provided which is dimensioned to block the circular opening in the closed position. The plate can be moved and rotated to a fully open position. The plate is rotated by an actuator and movement of the damper plate is controlled by a coupling mechanism. This mechanism can have a pair of spaced guide plates each of which is provided with two arcuate, diverging guide slots. Corresponding guide slots in the two plates are aligned. A support bracket for the damper plate has two guide pins which extend through the aligned slots and are movable therein. <IMAGE>
