Abstract
SOPRADOR TIPO ROOTS COM UMA CONFIGURAçãO DE REDUçãO DE RUìDO E MéTODO PARA CONFIGURAR UM TRAJETO DE FLUXO DE GáS PARA FORNECER UM FLUXO DE GáS ENTRE UM ORIFìCIO DE UM SOPRADOR TIPO ROOTS E UMA CáMARA DE TRANSPORTE DE GáS Um soprador tipo Roots compreende um alojamento que define uma câmara do rotor e uma entrada e uma saída da câmara do rotor. Primeiro e segundo rotores são montados na câmara do rotor, cada rotor definindo uma pluralidade de lóbulos, lóbulos adjacentes e o alojamento cooperando para definir câmaras de transporte de gás. O soprador é configurado para que uma vazão líquida de gás para uma câmara de transporte de gás seja em geral ou aproximadamente constante, por meio do que uma mudança na pressão de gás na câmara de transporte de gás é em geral ou aproximadamente linear, à medida que a câmara de transporte de gás aproxima-se da saída. Em uma modalidade, isto é obtido provendo-se canais de fluxo que estendem-se da saída em direção à entrada, e da entrada em direção à saída, correspondentes a cada rotor. Os canais de fluxo permitem que gás escoe da saída de alta pressão para uma câmara de transporte de gás, e da câmara de transporte de gás para a entrada de baixa pressão. A atenuação resultante de surtos de pressão associados com refluxo reduz substancialmente o nível de ruído operacional do soprador.
