VARIABLE CAPACITY TYPE NOZZLELESS TURBINE

摘要

PURPOSE:To vary the amount of working fluid and improve the efficiency of a turbine by providing a moving element for a volute casing of a variable capacity type nozzleless turbine. CONSTITUTION:A volute casing 10 is made up by two casings 10A, 10B. A working fluid conduit 12 runs from the tip 110 and is communicated with a turbine moving vane 20. An axis 11B is supported on the casing 10 and connected with a moving element 11 including a bellow 11A which varies the sectional area of the conduit 12.
