Abstract

Un ventilateur de tirage possède un boîtier monté dans un mur avec un conduit de sortie qui se prolonge à travers le mur vers une ouverture dorifice de sortie à lextérieur du mur. Un volet amortisseur est monté sur le ventilateur suspendu par une charnière sur le bord supérieur pour sétendre dans une position fermée à travers lorifice et est mobile vers une position ouverte sous leffet dun flux dair vers lavant depuis le ventilateur, et assure une fermeture hermétique contre un joint déformable élastique lorsque le ventilateur est à larrêt. Un agencement de sollicitation à ressort applique une force vers lintérieur au volet amortisseur pour solliciter le volet amortisseur vers la position fermée, et également une force vers lextérieur pour solliciter le volet amortisseur vers la position entièrement ouverte. Ces forces du ressort sont indépendamment réglables. À une faible vitesse de ventilateur, un élément de butée maintient le volet amortisseur dans une position partiellement ouverte contre la sollicitation de ressort à la position fermée.
