Abstract (en)
[origin: US2013094955A1] A centrifugal compressor diffuser includes a shroud-side wall (58) provided downstream of a centrifugal impeller; a hub-side wall provided so as to face the shroud-side wall (58); a plurality of shroud-side blades (3) fixed at base ends thereof to the shroud-side wall (58) and hub-side blades (4) fixed at base ends thereof to the hub-side wall. The shroud-side blades (3) and the hub-side blades (4) are combined in such a state that inlet angles thereof differ from one another and that at least portions of top ends thereof in a blade height direction are abutted onto one another. In gaps where the top ends of the combined shroud-side blades (3) and hub-side blades (4) are not abutted onto one another, a connecting member (5) that connects the top ends is provided so as to fill at least portions of the gaps.
