Abstract

"SILENCIADOR PROVIDO DE UM RESSONADOR DE DERIVAçãO". Sendo formado por um volume de carcaça externa que abrange o canal condutor de som (1) em uma área pré-determinada. o canal condutor de som (1) é conectado ao ressonador em derivação (10) através de furos (6). Os furos no canal condutor de som (1) são constituídos de elementos tubulares (6), preferivelmente em uma pega moldada por injeção (5), os quais se estendem desde o canal condutor de som (1) até o volume de carcaça do ressonador em derivação (10).
