Abstract:
PCT No. PCT/JP95/00411 Sec. 371 Date Sep. 10, 1997 Sec. 102(e) Date Sep. 10, 1997 PCT Filed Mar. 13, 1995 PCT Pub. No. WO96/28662 PCT Pub. Date Sep. 19, 1996A highly efficient centrifugal type fluid machine is configured so that the vane outlet angle or the vane outlet diameter at a side plate end (4a) of a single stage or a plurality of stages of a diffuser (D) is made larger than the vane outlet angle or the vane outlet diameter at a core plate end (4b), and the vane curve at a pressure surface end of a single stage or a plurality of stages of the diffuser (D) is formed to have the same radius of curvature at the side plate end (4a) and at the core plate end (4b), while the vane curve at a negative pressure surface end is formed to have a radius of curvature so that the vane thickness at the core plate end (4b) is larger than that at the side plate end (4a).
