Abstract

L'invention concerne la fourniture d'une plaque d'absorption conçue de manière à pouvoir empêcher le bruit provoqué par la récupération élastique d'un élément d'étanchéité souple de celle-ci lorsque la plaque d'absorption revient vers son état d'origine depuis un état dans lequel le conduit d'air d'un élément de retenue a été fermé par l'élément d'étanchéité souple placé en contact élastique avec la surface périphérique interne du conduit d'air. Une plaque d'absorption (20) est disposée de manière rotative dans un élément de retenue (5) d'un registre (1) entre une paroi gauche (6) et une paroi droite (7) d'un conduit d'air (1) afin d'ouvrir et fermer le conduit d'air (10), qui guide l'air vers une sortie d'air (12) du registre (1). Sur la plaque d'absorption (20), des saillies (56) d'une première partie d'étanchéité (50) et des saillies (66) d'une seconde partie d'étanchéité (60) sont formées par un élément d'étanchéité souple (40) le long de la bordure de la plaque d'absorption (20) et font saillie dans une direction perpendiculaire à un corps de plaque (31) d'un élément de plaque (30).
