Abstract
A centrifugal compressor has a plurality of seals arranged at the back of an impeller for sealing the impeller outlet and form an annular space defined at the back of the impeller. The annular space is fed with a cold gas under a higher pressure than that of the air discharged at the impeller outlet. Thus, the back of the impeller is cooled down.
