1. A centrifugal compressor that compresses a working fluid, comprising:
an impeller comprising alternately arranged full blades and splitter blades, the splitter blades being shorter than the full blades; a shroud wall forming an intake and having a shape conforming to the impeller; and a bleed chamber that communicates with a discharge space having a pressure equal to or lower than a pressure of the working fluid at the intake, the bleed chamber facing an outer surface of the shroud wall,wherein
the shroud wall is provided with 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, and in a meridional projection obtained by rotationally projecting the full blade, the splitter blade, and the shroud wall on a meridian plane passing through a rotational axis of the impeller, a point of intersection of an upstream edge of the splitter blade and an outward edge of the splitter blade is located at a position closer to the intake than an intake-side edge of an opening of an inlet of the bleeding passage. |
