The invention relates to a valve (10) for controlling the internal pressure p in a cabin of an aircraft, comprising a first flap (11) and a second flap (12), wherein the flaps (11, 12) control a pressure-changing fluid flow (L) between the surroundings and the cabin through an opening (15) of a limi
The invention relates to a valve (10) for controlling the internal pressure p in a cabin of an aircraft, comprising a first flap (11) and a second flap (12), wherein the flaps (11, 12) control a pressure-changing fluid flow (L) between the surroundings and the cabin through an opening (15) of a limiting element (14) of the cabin. In order to increase the inflow volume of the fluid, according to the invention at least one of the flaps (11, 12) is adjustable in the inflow position in respect of the opening (15) in the direction of the surroundings, such that the flow surface of the flap (11, 12) is increased for the air flow (L). Furthermore according to the invention at least one of the flaps (11, 22) has a closure device (21) which reduces an outflow of the fluid that had previously flowed in during an inflow process. According to the invention, a closure-device (21) is furthermore arranged, wherein said closure device closes a region between the first flap (11) and the second flap (12) in the inflow position of the flaps (11, 12).

1. A valve for controlling the internal pressure in a cabin of an aircraft, comprising: a first flap and a second flap, which are movably mounted in a frame; wherein the flaps control a pressure changing fluid flow between the environment outside the aircraft and the cabin inside the aircraft through an opening in the valve bounded by the frame; and wherein the first flap is mounted at a distance from a front edge of the frame and the second flap is mounted on a rear edge of the frame; the first and second flaps being movable to an open position defining (a) an inflow passageway within the opening between the front edge of the frame and the first flap and (b) an outflow passageway within the opening between the first and second flaps; the first and second flaps being movable from the open position through a closed position by which both the inflow passageway and the outflow passageway are progressively closed off, wherein the second flap is movable from the closed position through the open position without opening a fluid flow passageway between the second flap and the rear edge of the frame; and further comprising a closure flap that is mounted on one of the first flap, the second flap, and the frame and is movable for closing the outflow passageway in the open position of the first and second flaps to prevent fluid flow from the cabin inside the aircraft to the environment outside the aircraft along the outflow passageway while fluid flow from the environment outside the aircraft to the cabin inside the aircraft takes place along the inflow passageway, wherein the closure flap extends between the first flap and the second flap for closing the outflow passageway in the open position of the first and second flaps. 2. The valve as claimed in claim 1, in which the closure flap is arranged in a pivotally movable manner on one of the flaps. 3. The valve as claimed in claim 2, in which the closure flap is arranged on the first flap. 4. The valve as claimed in claim 3, in which the first flap is pivotable in a first direction for opening the inflow passageway and the closure flap is pivotable in an opposite direction for closing the outflow passageway. 5. The valve as claimed in claim 1, in which the closure flap is connected to a controllable actuator. 6. The valve as claimed in claim 1, in which the closure flap is mounted in a pivotally movable manner on the frame of the valve. 7. The valve as claimed in claim 6, in which the first and second flaps include top edges, which, in the open position of the first and second flaps, are arranged face toward the inside of the aircraft, and the closure flap, in the open position of the first and second flaps, bears against the top edges of the first and second flaps for closing the outflow passageway. 8. The valve as claimed in claim 6, in which the closure flap is connected by a linkage mechanism to at least one of the second flap and the frame. 9. The valve as claimed in claim 8, in which the linkage mechanism comprises at least one rod and coupling portions, which coupling portions are arranged on at least one of the second flap and the frame. 10. The valve as claimed in claim 8, in which the closure flap is pivotable via the linkage mechanism in opposite directions. 11. The valve as claimed in claim 6, in which the closure flap has lateral longitudinal margins having curved marginal regions. 12. The valve as claimed in claim 11, in which at least one of the marginal regions bears against the frame in the open position of the first and second flaps. 13. The valve as claimed in claim 1, in which at least one of the first and second flaps is mounted displaceably with respect to the opening. 14. The valve as claimed in claim 13, in which an actuator provides for displacing at least one of the first and second flaps. 15. The valve as claimed in claim 1, in which the first flap has an angled-off region. 16. The valve as claimed in claim 1, in which at least one of the flaps is variable in length. 17. The valve as claimed in claim 1, in which the first flap has a spoiler, which is adjustable with respect to the first flap by means of an actuator. 18. The valve as claimed in claim 1, in which the first flap is arranged on a swivel mechanism, so that the first flap is pivotally movable within the opening of the valve. 19. The valve as claimed in claim 18, in which the swivel mechanism has two supporting arms mounted in a pivotally movable manner on the frame. 20. The valve as claimed in claim 1, comprising an actuating device by which the closure flap is movable into engagement with at least one of the first and second flaps for closing the outflow passageway. 21. The valve as claimed in claim 20, in which the first and second flaps are arranged to be pivoted in opposite directions for approaching the open position of the valve.
