Abstract
A cooling system for a gas turbine engine includes a first structure movable relative to a second structure. The first structure has a cavity. A valve selectively controls fluid flow from a cooling source to the cavity. A valve is configured to move between first and second fluid flow positions in response to movement of the first structure. The first fluid flow position provides a greater amount of cooling fluid from the cooling source to the cavity than in the second fluid flow position.
