EXPANSION TURBINE FOR REFRIGERATING CYCLE

摘要

PROBLEM TO BE SOLVED: To provide an expansion turbine for a refrigeration cycle, increasing energy recovering efficiency during expansion in a simple structure.

SOLUTION: The expansion turbine 10 is provided with a disc-shaped base part 11, and a plurality of outer circumferential projecting parts 12 extended diametrically from the base part 11. The outer circumferential projecting part 12 has a jet applying surface 121, and an outer circumferential surface 122. The jet applying surface 121 is almost parallel to the diametric direction of the disc-shaped base part 11, and the outer circumferential surface 122 is formed to be almost perpendicular to the jet applying surface 121.
