Claim Text:
1. A thrust recovery outflow valve, comprising: a valve frame configured to be mounted on an aircraft exterior skin, the valve frame including an inner surface that defines opening through the valve frame; a first valve door rotationally mounted on the valve frame and rotatable between a first door closed position and a plurality of first door open positions; a second valve door rotationally mounted on the valve frame, the second valve door rotatable independent of the first valve door, the second valve door rotatable between a second door closed position and a plurality of second door open positions; a flap rotationally mounted on only the first valve door, the flap rotatable between a stowed position and a deployed position, the flap disposed adjacent to the first valve door when the flap is in the stowed position, the flap rotated away from the first valve door and toward the second valve door when the flap is in the deployed position, the flap moved from the stowed position to the deployed position when the first valve door is rotated to a first predetermined open position; a first actuator input structure coupled to, and extending from, the first valve door, the first actuator input structure adapted to receive a drive force and to transfer the received drive force to the first valve door; a stop pin coupled to, and extending from, the first actuator input structure, the stop pin engaged by the flap only when the flap is out of the stowed position; a flap engagement pin extending through the first actuator input structure and movable between a hold position, in which the flap engagement pin will hold the flap in the stowed position, and a release position, in which the flap engagement pin will not hold the flap in the stowed position; and an actuation pin coupled to the valve frame and configured to engage the flap engagement pin, and thereby move the flap engagement pin from the hold position to the release position, only when the first valve door is rotated to the first predetermined open position.
