ABSTRACT:
A hydraulic turbine is disclosed having wicket gate vanes which are rotatable between extreme positions to interrupt and permit the flow of water through a substantially cylindrical water passageway. In order to effectively block the flow of water through the passageway, the outer peripheral surface of the vanes must have a spherical configuration to match the circular cross-section of the cylindrical passageway. However, with this configuration, when the vanes are in an open position, a vee-shaped space is defined between the ends of the vanes and the water passageway. Baffles are provided to fill this space so that debris cannot collect therein.
