ABSTRACT:
An induction type air outlet device comprises a ring of air outlet nozzles and a central passage in a partition of a housing. The air outlet nozzles are directed to the peripheral portions of an air guide blade assembly and entrains room air which enters through the central portion of this assembly. A pair of spring loaded flaps close the central passage. When the supply of fresh air to the device is increased beyond a certain level, the flaps are deflected and form a roof-shaped structure. Thus fresh air flowing through the passage blows against an increased area of the air guide blade assembly, whereby the ratio of fresh air and entrained room air is increased. The flaps are coupled through elongated toothed bodies.
