Abstract

"ABAFADOR PARA A ATENUAçãO DE RUìDO PRODUZIDO EM UM ORIFìCIO DE EXAUSTãO DE UM DISPOSITIVO PNEUMáTICO, PROCESSO DE FABRICAçãO DO MESMO, E, DISPOSITIVO DE VáLVULA PNEUMáTICA". Um abafador para a atenuação de ruído produzido por um dispositivo pneumático tendo folga limitada. O abafador inclui um alojamento e um material de barreira acústica. O alojamento inclui uma entrada e uma saída. Em uma forma de realização preferida, ao menos uma porção do alojamento é tronco-cónica, de modo que a saída tem uma largura maior do eu o diâmetro da entrada. Também, o alojamento tem preferentemente uma largura máxima menor do que aproximadamente 38 mm (1,5 polegada). O material de barreira acústica é disposto dentro do alojamento e forma uma pluralidade de microbolhas. Ademais, o material de barreira acústica é configurado para se conformar a uma forma do alojamento. O abafador pode ser utilizado com uma vá pneumática tendo espaço limitado disponível para a recipiente do abafador, provendo significante redução de ruído com contrapressão mínima.
