Abstract
The centrifugal compressor includes an impeller configured to feed a fluid suctioned from one side to an outside in a radial direction by rotating about an axis, and a flow path provided between the impellers adjacent to each other in the direction of an axis and configured to guide the fluid discharged from an impeller on the upstream side to an impeller on the downstream side. The flow path includes a diffuser flow path, a return bend portion, and a guide flow path. Further, the centrifugal compressor further includes return vanes extending across the return bend portion and the guide flow path in the flow path and provided in intervals in a circumferential direction, and the radial positions of the leading edges of the return vanes in the flow paths adjacent in the direction of the axis are different from each other.
