Abstract

TRAJETO DE FLUXO DE GáS DE ATENUAçãO DE RUìDO PARA UM COMPRESSOR TUBO PERFURADO DE ATENUAçãO DE RUìDO E SISTEMAS DE MONTAGEM E DE ATENUAçãO DE RUìDO PARA UM COMPRESSOR A invenção compreende um método e aparelho para reduzir o ruído gerado por compressores, incluindo sopradores tipo Roots. A invenção tem uso particular para reduzir ruído gerado por compressores usados em ventiladores mecânicos, embora suas vantagens possam ser concretizadas em muitas diferentes aplicações. Uma modalidade da invenção compreende um trajeto de fluxo de gás de atenuação de ruído para um compressor contido em um alojamento de ventilador portátil. Em uma modalidade, o trajeto de fluxo de gás compreende uma pluralidade de câmaras interconectadas por tubos de fluxo. O trajeto de fluxo é dobrado de maneira a se encaixar no espaço limitado de um alojamento de ventilador portátil. As dimensões das câmaras e dos tubos de fluxo são selecionadas para que seja criado um desencontro de impedâncias entre as câmaras e os tubos de fluxo. Em uma modalidade da invenção, o trajeto de fluxo compreende um ou mais tubos perfurados localizados em uma ou mais das câmaras, O tubo perfurado tem um furo através do qual gás é aceito e pelo menos um tubo exterior através do qual gás sai. Desencontros de impedância são criados entre a câmara de entrada e os tubos exteriores e entre os tubos exteriores e a câmara na qual o tubo perfurado fica localizado, que são usados na atenuação de ruído. Uma modalidade da invenção compreende um sistema de montagem de atenuação de ruído para um compressor. O sistema de montagem compreende montagens flexíveis que cooperam para amortecer vibrações geradas pelo compressor.
