機の性能可変装置。 The centrifugal compression section has multiple stages, and return guide vanes are provided at appropriate intervals in the circumferential direction within the annular return passage connecting the discharge port of the compression section located at the previous stage and the suction port of the compression section located at the next stage. In the multi-stage compressor, the return guide vane is divided into two in the radial direction, one of the divided vanes is fixed in the return passage, and the other vane is provided so as to be rotatable in the circumferential direction. Features a multi-stage compressor performance variable device.
