Abstract
In this centrifugal compressor, when a passage cross-section of a bypass passage at a connection point where the bypass passage and a compressor inlet passage are connected to each other is defined as an outlet cross-section of the bypass passage, a range of the outlet cross-section on the downstream side of the center of the outlet cross-section in the axial direction of an impeller and on the upstream side of the center in the rotation direction of the impeller is defined as a first range, and a portion of a passage wall surface of the bypass passage at the outlet cross-section that belongs to the first range is defined as a first-range wall surface portion, at least the first-range wall surface portion of the passage wall surface of the bypass passage at the outlet cross-section is formed from a curved line.
