Wicket gate
From Wikipedia, the free encyclopedia
A wicket gate is a small gate or door, particularly one built into a larger one.
The cricket term wicket comes from this term.
Wicket gates are also a key component in hydroelectric turbines that control the flow of water from the input pipes (Penstock and then the Squirrel Cage) to the turbine propellers (Runners).
