An air distributor (1) comprises an upper part (2), which consists of a planar bottom part (4) and a connection piece (3) for incoming air, at which upper part (2) a perforated distribution disk (6) is attached by means of quick-fixing devices (9). On the inner side of the distribution disk (6) a control disk (17), made of a flexible or metallic material, is attached in several points in a variable manner. The control disk (17) can be entirely removed or exchanged for another one, designed in another way. Through various adjustments in the various fixing points in relation to the distribution disk (6) various distribution patterns for the incoming air and the coejected secondary air are obtained. The variable fixing means consist of bolts (20), provided with round about grooves (22), in combination with cross holes (21) in the control disk (17). |
