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