Abstract
A centrifugal compressor includes: a compressor housing; an impeller wheel for compressing intake air, disposed inside the compressor housing; a parallel flow generating unit for rectifying the intake air flowing in via an intake port to be parallel to the direction of a rotation shaft; and a recirculation channel for returning a part of the intake air in an outer circumferential section of the impeller wheel to an upstream side of the impeller wheel. The parallel flow generating unit includes a parallel flow generating part including a plurality of guide vanes and a central intake-air flowing section which is a space surrounded by the parallel flow generating part. An intake-air outflow direction from an upstream opening is oriented toward the parallel flow generating part.
