Abstract
Provided is an annular compressor cover forming a passage wall of a diffuser passage in a centrifugal compressor, wherein, when the end-of-winding position of a scroll passage of the centrifugal compressor is defined as the 360° position of the compressor cover in the circumferential direction, the direction in which a fluid flows through the scroll passage in the circumferential direction is defined as the positive direction of positions in the circumferential direction, and the distance between outlets of the diffuser passage at each position in the circumferential direction and the central axis of the inner circumferential surface of the compressor cover is defined as the diffuser radius, the average value of the diffuser radius in a range up to 180° from the position of a tongue section of the scroll passage in the circumferential direction is smaller than the average value of the diffuser radius in a range from 180° to 360° in the circumferential direction.
