摘要

The air inlet, outlet and/or distributor for room ventilation has a rectangular housing with air apertures in one or more longitudinal walls. A swivel flap inside the housing connects with the apertures, to shut off or direct the air flow. In the open position it is at an acute angle to the wall containing the apertures. Two longitudinal walls at right angles form a corner (6) fitting into the room corner. The flap (10) swivels w.r.t. the wall (7) containing the apertures (11) near the edge of one of the walls (6b) forming the corner away from the latter (7f,10b). In the open position, the flap is at an obtuse angle to the room surface (12,25), extending from the wall contg. the apertures.
