PURPOSE:To absorb the difference in thermal expansion between a radial nozzle and a block in a radial turbine in order to prevent the radial nozzle from being damaged, by inserting a heat resisting elastic body between the radial nozzle and the block. CONSTITUTION:A moving vane 2 rotates within a space formed by a radial nozzle 4, a block 10, and a casing 9. A ring-shaped, heat resisting elastic body 13 is inserted between the radial nozzle 4 and the block 10 so that the radial nozzle 4 is pushed outward. With these contrivances, the difference in heat expansion between the radial nozzle and the block is absorbed, which prevents the clearance or excessive stress from occurring. |
