Abstract
A rotary machine includes a thrust bearing and radial bearings rotatably supporting a rotary shaft, a rotation drive portion that rotates the rotary shaft, a first-stage impeller that rotates about an axis of the rotary shaft, a casing, a working fluid gas extraction portion that extracts a working fluid under compression from a middle of the first-stage impeller to an outside of the casing, and a working fluid supply line that allows the working fluid under compression, on which gas extraction is performed by the working fluid gas extraction portion, to be supplied therethrough to the rotation drive portion.
