Abstract
The invention relates to a valve for controlling the internal pressure in a cabin of an aircraft. First and second flaps supported in a frame control a fluid flow between the environment and the cabin through an opening of the valve. The first flap is supported at a distance from a front edge of the frame and the second flap is supported on a rear edge of the frame. A closing device closes an outflow opening (56) in an inflow position of the flaps, which outflow opening is bounded by the flaps. The closing device is pivotably supported on one of the flaps, and interacts with the locking device in such a way that the closing device closes the outflow opening in the event of a pivoting motion of the flaps.
Claims20
A valve for controlling the internal pressure in an aircraft cabin, comprising:
- a first flap and a second flap supported in a frame, wherein the first and second flaps control a pressure-changing fluid flow between the aircraft cabin and an environment outside the aircraft cabin through an opening of the valve,
- the first flap being supported at a distance from a front edge of the frame and the second flap on a rear edge of the frame,
- a closing device which, in an inflow position of the first and second flaps, closes an outflow opening delimited by the first and second flaps,
- the closing device being pivotably supported on one of the first and second flaps, and
- a locking device, which cooperates with the closing device in such a way that the closing device closes the outflow opening during a pivoting movement of the first and second flaps.
