ABSTRACT:
An apparatus for influencing a flow of air through a passageway defined between an inner wall and a double outer wall that includes first and second walls each formed with an opening, comprises a first door, a second door, vortex generation means positioned between the first and second walls and adjacent the upstream end of the opening in the first wall, and an actuator pivotally attached to the first and second doors. The actuator has a first condition wherein the first and second doors close the openings in the first and second walls respectively and has a second condition wherein the first door is at the downstream end of the opening in the first wall and extends across the passageway and directs the flow of air through the opening in the first wall, and the second door is at the down-stream end of the opening in the second wall and deflects the flow of air through that opening.
