Abstract (en)
[origin: EP0690272A2] Apparatus is described for regulating the flow of gas or air under pressure between two regions (A,B). The apparatus comprises a wall (10) which separates the two regions (A,B) and which has an aperture (12) through which gas or air flow is regulated by a regulating flap (14). The apparatus is characterised by the provision of irregularities on one or more surfaces (22,24) adjacent to which the air or gas flows, the irregularities serving to reduce the generation of noise. <MATH>
