Abstract

um compressor parafuso sem óleo tem um rotor de parafuso incluindo um parafuso e um eixo, um mancal sustentando o eixo, um primeiro dispositivo de ve-dação de eixo disposto entre o parafuso e o mancal e incluindo uma primeira veda-ção oposta ao eixo, e uma primeira porção de comunicação comunicando o lado de mancal com relação ao espaço entre o eixo e a primeira vedação e a face periférica externa do primeiro dispositivo de vedação de eixo, e um segundo dispositivo de vedação de eixo disposto entre o primeiro dispositivo de vedação de eixo e o mancal e incluindo uma segunda vedação oposta ao eixo, e uma segunda porção de co-municação comunicando o lado de parafuso com relação ao espaço entre o eixo e a segunda vedação e a face periférica externa do segundo dispositivo de vedação de eixo. um invólucro inclui uma porção de comunicação de atmosfera conectada tan-to à primeira porção de comunicação quanto à segunda porção de comunicação na face periférica interna de um espaço de acomodação de eixo, e comunicando a primeira porção de comunicação e a segunda porção de comunicação com a at-mosfera.
