| 摘要 |
The present invention relates to a system and method for equalizing an overpressure in the interior (6) of an aircraft cabin with respect to the exterior (5) of the aircraft. The system comprises a fluid flow path (7) adapted for providing fluid communication between the interior (6) of an aircraft cabin and the exterior (5) of the aircraft and a check valve (8) having an opened state and a closed state. The check valve (8) is arranged and adapted to enable fluid flow through the fluid flow path (7) from the interior (6) of the aircraft cabin to the exterior (5) of the aircraft and to block fluid flow through the fluid flow path (7) in the reverse direction when the check valve (8) is in the opened state, and block fluid flow through the fluid flow path (7) in both flow directions when the check valve (8) is in the closed state. The system also comprises a control means (9) operatively coupled to the check valve (8) and adapted for controlling the check valve (8) to switch between the opened state and the closed state. |
