Claims

[Scope of utility model registration request]

In a once-through water turbine in which the amount of inflow water is adjusted by rotating a curved water mouth partition plate located along the outer circumference of the runner about an axis parallel to the runner axis to freely open and close the water port of the water turbine, the water mouth partition plate is A once-through water turbine characterized in that the center of rotation of the water port partition plate is offset from the center of rotation of the runner so that the water port partition plate moves away from the outer periphery of the runner when the water port is opened.
