Abstract

PURPOSE: To eliminate hydrodynamic disadvantage by providing a diffuser vane at the outlet of a runner so that the transfer path of the inlet end of the vane may position close to a supposed circumferential line cocentric with the runner.
CONSTITUTION: The fitting place of a diffuser vane 6 on a vane fitting plate 5 is set so that the transfer path of the inlet end may position very close to supposed circumferential line A when the vane 6 oscillates in positive and negative directions from reference place 0. When the plate 5 is rotated by a rotary shaft 4, vane 6 can be oscillated in positive or negative direction from reference place 0. At this time, the transfer path of the inlet end of the vane 6 positions very close to supposed circumferential line A so that the outflow air of the runner 1 can be let into the diffusers without causing any hydrodynamic trouble.
