Abstract
A centrifugal compressor having an improved efficiency is constructed by providing a diffusion channel and vanes downstream of a diffuser, the diffusion channel being coupled to the diffuser through a U-turn channel, the outlet side passage of the U-turn channel being made larger than the inlet side passage and the kinetic energy being recovered at the diffusion channel. Further improvement is achieved by providing guide vanes in the U-turn channel.
