摘要

1. Device for regulating the air flow in an installation for putting a fluid into contact with the atmospheric air, comprising, on the path of the air stream, at least one deformable closure means (6, 34, 54) comprising a case (11, 19a, 19b, 21, 35) which is deformable under pressure, characterised in that it comprises means for tensioning the case enabling it be changed from a closing position in which it closes off at least part of the air stream to an opening position in which its walls are closer together and leave a passage for the air stream ; in that each closure means comprises two parallel bars (12 and 13, 22 and 23, 36 and 37, 56 and 57) which are arranged inside the case, are connected thereto and can be moved with respect to one another under the action of the said tensioning means.
