Abstract

La présente invention concerne un dispositif d'atténuation acoustique (10) pour une ligne d'admission d'un moteur à combustion thermique équipée d'un turbocompresseur, caractérisé en ce qu'il comprend : - un conduit (2) d'acheminement de gaz possédant une paroi périphérique (3) munie d'au moins une ouverture traversante (4), ladite ouverture traversante (4) servant de logement à un élément de séparation (7), et - au moins une chambre périphérique (5) disposée autour du conduit (2) de manière à entourer totalement ou partiellement l'élément de séparation (7), dans lequel l'élément de séparation (7) est formé dans un matériau poreux de manière à permettre une circulation de gaz entre le conduit (2) et la chambre périphérique (5), et dans lequel la chambre périphérique (5) est au moins partiellement remplie avec un élément d'absorption acoustique (8).The present invention relates to an acoustic attenuation device (10) for an intake line of a thermal combustion engine equipped with a turbocharger, characterized in that it comprises: - a duct (2) for conveying gas having a peripheral wall (3) provided with at least one through opening (4), said through opening (4) serving as a housing for a separating element (7), and - at least one peripheral chamber (5) arranged around of the duct (2) so as to completely or partially surround the separation element (7), in which the separation element (7) is formed in a porous material so as to allow gas to flow between the duct (2) ) and the peripheral chamber (5), and in which the peripheral chamber (5) is at least partially filled with a sound absorption element (8).
