A bypass air valve is provided comprising a liner, a strap, and apparatus for selectively actuating the valve. The liner includes an inner surface, an outer surface, a plurality of first regions, and a plurality of second regions. Each first region includes a plurality of first apertures. The strap includes a plurality of openings and a plurality of third regions. The third regions include a plurality of second apertures. The valve may be selectively actuated into an open position where the first regions are in communication with the openings, and the third regions are in communication with the second regions. The valve may be selectively actuated into a closed position where the first regions are in communication with the third regions, and the second regions are in communication with the openings. The flow path through the first and second apertures in the closed position impedes flow substantially more than the flow path through the first apertures and the openings in the open position, thereby effectively closing bypass air flow through the valve in the closed position.

[ I claim:] [1.] A bypass air valve, comprising:a liner, having an outer surface, a plurality of first regions, each first region including a plurality of first apertures, and a plurality of impermeable second regions;a strap, surrounding said liner, having a plurality of openings and a plurality of third regions, said third regions including a plurality of second apertures;means for selectively actuating said valve;wherein said valve may be selectively actuated into an open position where said first regions are substantially aligned with said openings and said third regions are substantially aligned with said impermeable second regions, thereby providing a first flow path for bypass air surrounding said valve to pass through said valve via said openings and first apertures; andwherein said valve may be selectively actuated into a closed position where said first regions are substantially aligned with said third regions and said second regions are substantially aligned with said openings, thereby providing a second flow path for bypass air surrounding said valve through said valve via said second and first apertures, and exposing said second regions to said bypass air surrounding said valve; andwherein said second flow path is sized to impede passage of bypass air through said valve substantially more than said first flow path.
