摘要： A fluid compressor comprising a helical blade type compression mechanism that includes a cylinder (5), a roller (11) arranged inside the cylinder and a helical blade (15) interposed between the roller and the cylinder. The blade, the roller and the cylinder are formed of materials whose coefficients of thermal expansion satisfy relationships: Blade > Roller > Cylinder. According to this invention, pressure release can be easily performed in the case where the liquid flows back or under a low-temperature condition as at the time of actuation. In addition, the compression performance can be improved under a high-temperature condition during operation.
