The outlet (10) has a housing (16) with an air outlet aperture (18), a first terminal (20) at an air feed channel and a continuous flow channel (24). The continuous flow channel is provided with two opposite portions (26, 28), which are curved so that a cross-section of the flow channel is larger than the air outlet aperture. Apertures (30, 32, 34) are arranged behind the portions. Lying chambers (36, 38) for the first terminal and a second terminal (40) are opened for supplying or discharging air for generating overpressure and low pressure respectively. |
