Abstract

La présente invention concerne un silencieux d'échappement destiné à être monté à la sortie d'échappement d'un gaz moteur d'un dispositif actionné par ce gaz moteur. Le silencieux comporte une chambre de détente dans laquelle débouche la sortie d'échappement et qui communique avec l'extérieur par un passage pourvu d'un obturateur disposé pour faire office de diaphragme et dégager plus ou moins l'ouverture de passage en fonction de la pression et du débit de gaz dans la chambre et réalisé dans un matériau apte à amortir les variations cycliques de ladite pression. Le silencieux de l'invention trouve une application particulière aux outils portatifs ou moteurs pneumatiques, notamment aux meuleuses pneumatiques.
