Abstract

Amortissement de bruit de moteurs. Un amortisseur de son est constitué par une boîte 4 comportant une entrée 2 et une sortie 5 pour les gaz d'échappement d'un moteur à combustion interne et formant une chambre d'amortissement 12 est parcourue par les gaz d'échappement (flèches 16). Le volume et/ou la forme de cette chambre 12 sont variables en fonction de la composante de pression et vitesse des gaz d'échappement qui la traversent Application : silencieux pour moteur de véhicule.
