Abstract

PURPOSE: To improve the efficiency of a runner by a method wherein there is provided a blade which can revolve about the central axis and while the blade makes one revolution about the central axis it is allowed to make a half rotation.
CONSTITUTION: There are provided blades an, bn so that they can revolve about the central axis O and they are allowed to make a half rotation while they make one revolution about the central axis. Accordingly, when the flow of the Y-Y' direction strickes against these blades, torques, with its maximum at position O1, act clockwise at any other positions than the point O of the O4 and do not act in the negative direction. Thus, the efficiency of the runner can be improved.
