Abstract
L'invention concerne une bouche (1) d'extraction de gaz destinée à être montée dans une lumière d'une cloison, comprenant :
- un boitier (2) fixé à la cloison, doté d'ouvertures (4, 6) définissant un passage à travers le boitier pour la circulation d'un flux gazeux selon un sens d'extraction (E),
- une membrane (8) élastique en flexion, fixée au boitier selon une ligne (10) de fixation et s'étendant en regard d'au moins une partie des ouvertures,
caractérisée en ce que la membrane comprend :
• une feuille hydrophobe (9), élastique en flexion,
• au moins deux raidisseurs (12) de forme allongée, présentant un coefficient d'allongement en fonction de l'humidité supérieur à celui de la feuille hydrophobe (9),
• lesdits raidisseurs (12) étant fixés sur une face aval de la feuille hydrophobe (9), de manière à ce que l'allongement des raidisseurs en fonction de l'humidité du flux d'extraction s'oppose à une flexion de la membrane (8) vers l'aval sous l'effet dudit flux d'extraction.
The invention relates to a gas extraction mouth (1) intended to be mounted in a light of a partition, comprising:
- a housing (2) attached to the partition, having openings (4, 6) defining a passage through the housing for the circulation of a gas stream in a direction of extraction (E),
a flexible bending membrane (8) fixed to the housing along a fastening line (10) and extending facing at least part of the openings,
characterized in that the membrane comprises:
A hydrophobic sheet (9), elastic in flexion,
At least two elongate stiffeners (12) having a coefficient of elongation as a function of humidity greater than that of the hydrophobic sheet (9),
Said stiffeners (12) being fixed on a downstream face of the hydrophobic sheet (9), so that the elongation of the stiffeners as a function of the humidity of the extraction flow is opposed to a bending of the membrane (8) downstream under the effect of said extraction stream.
