Abstract

Le diffuseur 21 selon l'invention est encastré dans un plafond modulaire 23. Il comprend des volets 39 dont la position d'ouverture est modifiée par un ensemble détecteur-actionneur 71 sensible à la température et relié à une plaque de commande 45 reliée aux volets 39 par des tiges de manoeuvre 43. Dans le présent diffuseur, c'est la dilatation de la matière contenue dans le détecteur-actionneur qui fournit la force nécessaire pour ouvrir plus ou moins les volets 39.
