Abstract
A centrifugal compressor includes: an impeller having full blades and splitter blades; a shroud wall forming an intake and having a shape conforming to the impeller; and a bleed chamber facing an outer surface of the shroud wall. The bleed chamber communicates with a discharge space having a pressure equal to or lower than a pressure of a working fluid at the intake. The shroud wall is provided with a slit (a bleeding passage) that directs a portion of the working fluid that has flowed into a space between the full blade and a pressurizing surface of the splitter blade to the bleed chamber.
