Abstract

La présente invention concerne un silencieux pour gaz d'échappement. Silencieux caractérisé en ce qu'entre la chambre de sortie et la chambre tampon est disposée une deuxième chambre pompon à renversement d'écoulement qui communique avec la chambre d'entrée par un tube supplémentaire, plus court, ouvert aux deux extrémités, traversant la chambre de sortie et perforé dans une région partielle. L'invention est plus particulièrement applicable dans le domaine de la fabrication de silencieux pour moteurs à combustion interne.
