ABSTRACT OF THE DISCLOSURE The improved diffuser includes pinching a por- tion of a diffuser flow passageway that has ribs therein extending partially across the diffuser passa- geway and that have their leading edges located away from the inlet of the diffuser passageway. The dif- fuser passageway is pinched from the diffuser inlet to the leading edge of the ribs to provide improved flow angle alignment and the leading edges of the ribs been moved away from the impeller to avoid buffeting and noise as the compressed gas leaves the impeller and enters the annular diffuser passageway.
