Improvements to the devices ensuring the distribution and automatic regulation of air flows, in particular for the ventilation of premises.

摘要

The invention relates to a device for regulating the ventilation of premises comprising a flexible flat membrane (11) embedded on one of its sides inside the trunk (12) on its upper wall between the two opposite openings (18 ) and (19) that it comprises, said membrane bending under the effect of the air current passing through said trunk, to more or less seal one of the openings (18) or (19), its resistance to bending being made different according to its direction of stress by the presence of the stops (13) and (15) of different length on either side of its embedding, this difference can be increased by the presence of perforations of said membrane at the stop closest to the installation.
