Abstract
La présente invention concerne un silencieux pour moteurs à combustion interne. Ce silencieux comprend un conduit 1 véhiculant les gaz d'échappement et un tube d'enveloppe 2. Le volume 3 compris entre ces derniers est rempli d'un matériau 4 résistant à la chaleur, fibreux, avantageusement de laine d'acier chromé. Le conduit 1 s'élargit coniquement dans le sens d'écoulement des gaz et comprend sur sa surface une pluralité de fentes 5 dont les bords 6 sont arrondis vers l'extérieur. La plus grande partie de l'énergie du son, à haute fréquence, est guidée dans la couche de remplissage 4 et les gaz d'échappement peuvent s'écouler pratiquement sans obstacle. L'invention s'applique notamment aux moteurs d'avion.
