Abstract

PURPOSE: To enable to fill water to the entire region of water passage, by simplifying the air drawing structure by providing air drawing pipes on the outside of a vane return guide, and exhausting air to the outside efficiently.
CONSTITUTION: Air exhausting pipes 18 having respectively a control valve 17 are provided on the outside of a vane return guide 5. By opening the control valves 17 sinchronously with air exhausting signals and opening guide vanes 7, 8 appropriately, charging of water is started from the upstream side of the first-stage runner 2 and the downstream side of the second-stage runner 3, so that air 19 left in the return guide 5 can be discharged to the outside completely. Thus, it is enabled to charge water to the entire region of the water passage.
