Abstract
In an apparatus for distributing air flowing along a first path, the first path splits into second and third paths, so that both the second and third paths diverge from the first path. The second and third paths are at an angle of less than 180° to one another. A first door, is across the second path; and a second door, is across the third path. A common operating device rotates both doors, such that air is able to flow from the first path into the second and third paths, the flow being dependent on the position of rotation of the doors.
