Abstract

An apparatus for controlling the flow of air in an air duct structure includes a lamella unit in the air duct structure moveable between a plurality of positions for controlling the flow of air in the air duct structure. A rocking lever having a groove is pivotally mounted on the air duct structure for pivotal movement about a pivotal axis. The lamella unit has an engageable part disposed in the groove to provide an operable connection between the lamella unit and the rocking lever such that pivoting of the rocking lever about the pivotal axis effects movement of the lamella unit between the plurality of positions. An adjusting element is provided for effecting pivotal movement of the rocking lever about the pivotal axis. An air damper is also pivotally mounted in the air duct structure upstream of the lamella unit for movement between a closed position and an open position, and an operable connection is provided between the air damper and the rocking lever effecting movement of the air damper between the closed and open positions when the rocking lever moves the lamella unit between the closed position and the plurality of open positions.
