Abstract
In a piston-type compressor in which a working fluid is taken in through an intake port is first compressed with pistons and is then let out through an outlet port, an axial hole ranging along the axial direction and a radial hole communicating with the axial hole and opening into a crankcase are formed within the shaft. Additionally, a first intake passage through which the working fluid having flowed in through the intake port is guided via the crankcase to the radial hole and the axial hole and a second intake passage through which the working fluid having flowed in through the intake port is guided to join the working fluid having been drawn into the first intake passage by bypassing the crankcase are formed in the compressor. The working fluid is taken into cylinders from the area where the first working fluid and the second working fluid join each other.
