Abstract

La présente invention concerne un conduit (1) d'acheminement de gaz, tel qu'un conduit d'acheminement d'air turbo-comprimé pour moteur à combustion, ledit conduit (1) étant caractérisé en ce qu'il comprend au moins un tronçon (3, 5), dit « tronçon flexible », dont la section de passage (8) est délimitée latéralement par une paroi (10) qui comporte, dans son épaisseur, au moins une couche réalisée dans un silicone élastomère qui présente une masse volumique supérieure à 1,20 g/cm , et de préférence comprise entre 1,30 g/cm et 1,45 g/cm , de manière à atténuer les émissions sonores dudit conduit (1).The present invention relates to a pipe (1) for conveying gas, such as a pipe for conveying turbo-compressed air for a combustion engine, said pipe (1) being characterized in that it comprises at least one section (3, 5), called "flexible section", whose passage section (8) is delimited laterally by a wall (10) which comprises, in its thickness, at least one layer made of an elastomeric silicone which has a mass volume greater than 1.20 g / cm, and preferably between 1.30 g / cm and 1.45 g / cm, so as to attenuate the sound emissions of said duct (1).
