Patent attributes
A rotary machine includes a compression section that is disposed between the pair of radial bearings in a casing and compresses a fluid, an expansion section that is disposed side by side with the compression section and expands the fluid, and a thrust bearing that is disposed at a position close to a first end portion or a second end portion of a rotary shaft in an axial direction with respect to the compression section and the expansion section. Among a compression section suction port, a compression section discharge port, an expansion section suction port, and an expansion section discharge port, the compression section suction port is disposed at a position closest to the first end portion in the axial direction, and the expansion section discharge port is disposed at a position closest to the second end portion in the axial direction.
