Abstract (en)
Herein disclosed is a centrifugal compressor, in which a seal member (15) is arranged annularly and multiplexly at the back of an impeller for sealing up a gap between the impeller exit and back and forming an annular space (6), and in which the annular spacer is fed with a cold gas under a higher pressure than that at the impeller exit, so that the centrifugal compressor may have its impeller back cooled down. <IMAGE>
