A valve assembly 200 for supplying cooling air to a nozzle 113 of a gas turbine engine 100. The nozzle 113 can move between a first configuration and a second configuration. The valve assembly 200 includes a first member 215 having openings 217 that receive cooling air. The valve assembly 200 also includes a second member 207 having openings 213. The second member 207 resides adjacent the first member 215 to receive the cooling air from the first member. Finally, the valve assembly includes actuator 203 for moving the first member from a first position, which allows a first flow rate of cooling air to pass through the openings 213,217, to a second position, which allows a second flow rate of cooling air to pass through the openings 213,217. The second flow rate is less than the first flow rate. <IMAGE> |
