<P>PROBLEM TO BE SOLVED: To provide a centrifugal compressor that reduces leakage flow while suppressing an increase in weight of a rotor. <P>SOLUTION: The centrifugal compressor 2 includes an impeller 12, and a shroud housing 11c. The impeller 12 has a plurality of large and small blades 122, 123. The shroud housing 11c covers the plurality of large and small blades 122, 123 externally in the rotation-radial-direction of the impeller 12. The impeller 12 has fins 122b, 123b extending from radially outside ends of the large and small blades 122, 123 toward a rotation advancing direction R, respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
