Abstract

L'invention propose un élément terminal pour conduite d'échappement de gaz. L'élément comprend une enveloppe longitudinale (8) avec une entrée (7), une sortie (11), et un tuyau interne (13) concentrique s'étendant le long d'une partie de l'enveloppe (8), le tuyau (13) étant perforé latéralement et communiquant à une extrémité vers l'extérieur. L'entrée (7) de l'enveloppe communique directement avec un pot d'échappement (1) ou avec un élément de conduite des gaz d'échappement d'un moteur à combustion. Il est prévu dans l'élément terminal un obstacle au flux linéaire du gaz expulsé, obstacle que le dit flux contourne avant d'accéder à l'extérieur, en passant par le tuyau perforé (13) dont l'extrémité est de préférence tronconique. La sortie peut être intégrée ou adaptée à un pot d'échappement classique.
