摘要

An apparatus for the automatic control of ventilation of premises comprising a flexible flat membrane (11) attached by one of its edges in the interior of the casing (12) on the upper wall between two opposed openings (18) and (19). The upper wall supports the membrane. The membrane buckles and bends under the effect of an air current flowing through said casing in order to seal and block one of the openings (18) or (19) to a larger or smaller extent. The bending strength of the flexible planar membrane (11) is made different according to the direction of actuation of the membrane by the presence of the stops (13) and (15) which have a different length on both sides its attachment. This difference can be increased by the presence of perforations and holes in the membrane at the level of the stop closest to the attachments.
