Abstract
A centrifugal compressor includes a housing, a partition separating an empty space in a housing into a speed increaser chamber and an impeller chamber, an insertion hole provided in the partition to allow insertion of a high-speed shaft, a seal located in the insertion hole to seal a boundary between the partition and the high-speed shaft, and a bearing receptacle located in the partition. The partition includes a communication passage that allows communication between a portion of the insertion hole located closer to the speed increaser chamber than the seal and the bearing receptacle.
