Abstract

Patente de Invenção: <B>"COMPRESSOR DE FLUIDO"<D>. Compressor de fluido que compreende um mecanismo de compressão tipo lâmina helicoidal que inclui um cilindro, um rolete disposto dentro do cilindro e uma lâmina helicoidal disposta entre o rolete e o cilindro. A lâmina, o rolete e o cilindro são formados de materiais cujos coeficientes de expansão térmica satisfazem as relações: Lâmina>Rolete>Cilindro. De acordo com a invenção, aliberação de pressão pode ser facilmente executada no invólucro onde o líquido fluir ou encontra-se em uma condição de baixa temperatura, como no momento de atuação. Além disso, o desempenho de compressão pode ser aperfeiçoado em uma condição de alta temperatura durante a operação.Invention Patent: <B> "FLUID COMPRESSOR" <D>. Fluid compressor comprising a helical blade-type compression mechanism that includes a cylinder, a roller disposed within the cylinder and a helical blade disposed between the roller and the cylinder. The blade, roller and cylinder are made of materials whose coefficients of thermal expansion satisfy the relationships: Blade> Roller> Cylinder. According to the invention, pressure release can be easily performed in the enclosure where the liquid flows or is in a low temperature condition, such as at the time of actuation. In addition, the compression performance can be improved in a high temperature condition during operation.
