ABSTRACT:
A centrifugal compressor includes an impeller and a diffuser arranged around the outer periphery of the impeller and including a pair of annular, spaced diffuser plates defining a diffuser channel therebetween. A plurality of guide vanes are provided on at least one of the pair of diffuser plates to guide a low flow angle portion of a fluid flow introduced into the diffuser channel from the outlet of the impeller. The guide vanes each extend from the inlet of the diffuser channel to a position which does not exceed about one half the distance between the inlet and the outlet of the diffuser channel and have a height which is less than one half the spacing between the pair of diffuser plates.
