(under the class definition) Apparatus comprising a fluid connection between the working fluid* path and a fluid conducting path in a runner* blade*, a stator vane*, the runner* support (shaft*) or a member turning in the working fluid* path and discharging fluid across substantially the entire area of the working fluid* path.
(1) Note. The fluid* path in the blade*, vane*, shaft* or rotary member may be connected to a source of nonsystem fluid for passage into the working fluid* path.
(2) Note. The fluid circuit may be for any purpose; included are devices for boundary layer control or for heating or cooling a runner* blade* or stator vane*.
