Abstract

L'invention concerne un aérateur à double flux, du type dans lequel le flux d'air aspiré dans le local pénètre dans la partie centrale de l'aérateur, tandis que le flux d'air frais est introduit dans le local à la périphérie de l'aérateur. Selon l'invention, un organe divergent 15 formant déflecteur est fixé de façon étanche sur la cloison cylindrique 8. On évite ainsi tout recyclage vers l'extérieur de l'air frais pénétrant dans le local.
