Abstract
An air discharge installation for supplying air into the interior space of a vehicle, in which an air regulating element connected with an actuating device is arranged in a housing within the area of an air inlet opening. To provide an installation which requires a small structural space combined with good and reliable functioning and which further enables a metered control of the air space, the air regulating element includes at least two valve sections pivotally connected with each other which are adapted to be moved from a folded-together, open position in which the two valve sections are disposed one above the other, into an unfolded closing position by way of intermediate positions. The first valve section is rotatably supported at the housing with its end remote from the actuating device while the second valve section is connected with the free end of the first valve section by way of a pivot bearing; additionally, a lever with a pin is arranged at the second valve section which extends at a distance to the pivot bearing and cooperates with a guide track in the housing, whereby the actuating device engages at the first valve section.
