Abstract: PROBLEM TO BE SOLVED: To improve efficiency by suppressing work quantity of work lost for cooling to minimum. SOLUTION: A bypass air valve 20 has a liner 36 and a strap 34. The liner 36 has a plurality of first regions 46 and second regions 48. Each first region 46 has a plurality of first openings 52. Each second region 48 has a plurality of second openings 56. The strap 34 has a plurality of openings 78 and third regions 76. Each third region 76 has a plurality of third openings 80. When the valve is opened, the first region 46 is arranged in line with the opening 78. In addition, the third region 76 is arranged substantially in line with the second region 48. When the valve is closed, the first region 46 is arranged substantially in line with the third region 76, while the second region 48 is arranged in line with the opening 78.

Abstract: A bypass air valve for a gas turbine engine is provided which includes a liner 36, a strap 34, and means 40 for selectively actuating the valve. The liner 36 includes an inner radial surface 42, an outer radial surface 44, a plurality of first regions 46, and a plurality of second regions 48. Each first region 46 includes a plurality of first apertures 52. Each second region 48 includes a plurality of second apertures 56. The strap 34 includes a plurality of openings 78 and a plurality of third regions 76. Each third region 76 includes a plurality of third apertures 80. The valve may be selectively actuated into an open or a closed position. In the open position, the first regions 46 are substantially aligned with the openings 78 and the third regions 76 are substantially aligned with the second regions 48. In the closed position, the first regions 46 are substantially aligned with the third regions 76 and the second regions 48 are substantially aligned with the openings 78.
