Abstract

PURPOSE: To simplify construction, decrease cost and also prevent capacity from decreasing by forming a spiral channel engraved at a turbine disc in a direction opposite to its turning direction, and also a sealing part by a gas packing annulus.
CONSTITUTION: In a proper location of a turbine disc 1, a spiral channel 2 is engraved in a direction opposite to its turning direction and also a gas packing annulue 3 without fin, forming a sealing part along with the channel 2. Further, a sealing air passage is instituted interconnecting the sealing part 4 and a backside of the blade wheel. With an operation of the supercharger 1 the turbine disc 1 is revolved, a sealing action is generated by means of the sealing part 4 composed of the channel 2 and the gas packing annulus 3 and compressed air led from the back side 6 of the blade wheel via passage 5 and the gas leakage of the blade wheel via passage 5 and the gas leakage of the supercharger is prevented.
