ABSTRACT:
A centrifugal compressor is disclosed as including a case, a compressor chamber, and an impeller in the compressor chamber for compressing fluid from an inlet opening and forcing compressed fluid through an outlet opening. Moreover, the compressor includes an insert rotatably supported on the case. The insert is adjacent the impeller and serves to minimize catastrophic compressor failure that might otherwise occur as a result of contact between the impeller and compressor chamber wall.
