Abstract

Dans une buse d'air pour installations de ventilation ou de climatisation destinées notamment à l'habitacle de véhicules automobiles, le boîtier de buse comporte des lamelles qui pivotent l'une après l'autre autour d'un axe d'articulation dans le sens de l'écoulement, comme des jalousies, ainsi que des clapets pivotant perpendiculairement à ces lamelles autour d'axes d'articulation, comme des jalousies. Ces lamelles et clapets sont reliés par un élément de couplage, tandis qu'un organe de manoeuvre commun monté de manière mobile sur une lamelle et pivotant avec les clapets sert au pivotement des lamelles. Ces lamelles (5) et clapets (3) présentent, pour être manoeuvrés sans cliquetis dans le boîtier de la buse d'air et à une certaine distance des essieux articulés (6, 7), des pivots (11, 12, 16) solidaires, et les pivots (11, 12, 16) des lamelles (5) et les clapets (3) sont reliés entre eux indépendamment par un élément d'accouplement en forme de bande, tandis que les lamelle (5) et les clapets (3) sont tendus mutuellement dans le sens longitudinal par des éléments d'accouplement et peuvent s'appliquer et être maintenus élastiquement et avec souplesse sur la paroi intérieure (10) du boîtier de la buse d'air (1), ce qui provoque la formation de moments de frottement.
