The diffuser 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.
