<p>765,908. Centrifugal compressors; radialflow turbines. GARRETT CORPORATION. March 10, 1955 [March 22, 1954], No. 7049/55. Classes 110 (1) and 110 (3). In a centrifugal compressor or centripetal turbine, the outer edges 12 of the rotor blades 11 are disposed at an angle to the rotor axis 13, and guide vanes 14 have inner edges 15 substantially parallel to the edges 12 and are pivoted about axes 21 which intersect the edges at a location between the limits thereof and preferably at about the mid-length of the edges. The axes 21 are parallel to the axis 13. This construction maintains a substantially constant clearance between the vanes 14 and the blades 11 over a wide range of angular adjustment of the vanes. The inclination of the edges 12 is such that the flow path adjacent the rotor disc 24 is substantially equal in length to that adjacent the casing wall 25.</p> |
