ABSTRACT:
A compressor is disclosed are disposed in which a diffuser flow passage is curved to a radial direction in the vicinity of an outlet of a mixed-flow impeller, and guide vanes are disposed in which each is of a height (projecting into the diffuser flow passage in a direction substantially transverse to the direction of flow) that is less than the meridional flow passage width such that the minimum inlet radius is larger than a maximum radius at the outlet of the mixed-flow impeller and are arranged in the form of a circular cascade at the curved portion on a flow passage surface of the diffuser plate located on a shroud side. Thus, it is possible to keep uniform the flow within the diffuser and to enhance the performance of the compressor. In addition, the axial length of the compressor may be shortened to thereby make the compressor compact in size.
