Abstract
An air vent is described, having a housing with an air discharge opening, a first connection to an air supply channel and a continuous flow channel. The flow channel is curved at least at two opposite sections such that the cross-section of the flow channel increases toward the air discharge opening, and the at least two sections (26; 28) have openings (30, 32, 34), each of which opens into a chamber located behind the sections. Each chamber has a second connection, separate from the first connection, for supplying or removing air so as to generate an overpressure and/or vacuum.
