Abstract

a presente invenção refere-se a um amortecedor acústico (24,30), para descarregar ar comprimido de uma válvula (28) de um sistema de tratamento de ar comprimido de um automóvel e para amortecer os ruídos de saída de fluxo, que apresenta uma carcaça (40), com pelo menos uma abertura de entrada (50) e pelo menos uma abertura de saída (52), bem como um material redutor de som (54), disposto na carcaça (40), entre a pelo menos uma abertura de entrada (50) e a pelo menos uma abertura de saída (52), para redução de ruídos de corrente de um ar comprimido, que se expande na carcaça (40) e que permeia o material redutor de som (54). para redução das emissões de ruído, o material redutor de som (54) apresenta uma densidade de enchimento mais alta na região central (58), adjacente a pelo menos uma abertura de entrada (50), do que na região externa (60), adjacente a pelo menos uma abertura de saída (52).
