Abstract

L'invention concerne un dispositif d'atténuation des bruits sur un circuit d'admission d'air pour moteur (10) à combustion interne suralimenté, ces bruits étant notamment issus du fonctionnement du turbocompresseur (11), ce dispositif se présentant sous forme d'une section (1) de conduit intégrable au circuit, ce conduit (1) étant équipé d'un premier groupe de chambres (5) circonférentielles externes, disposées en parallèle autour du conduit (1) et communiquant avec ce dernier par l'intermédiaire d'ouvertures (2) disposées en parallèle autour de la section de conduit (1).
Ce dispositif est caractérisé en ce que le conduit (1), apte à constituer une section du conduit du circuit d'entrée d'air du turbocompresseur (11), comporte au moins une chambre (6) supplémentaire disposée en série avec le premier groupe de chambres (5), ce premier groupe de chambres (5), destiné à l'atténuation des bruits haute fréquence, étant constitué de chambres s'étendant le long du conduit suivant une composante essentiellement axiale par rapport à l'axe longitudinal du conduit.
