  • Cabin pressure control system, method of controlling the actual pressure inside a cabin and outflow valve
    Patent number: 6746322
    Abstract: The invention relates to a cabin pressure control system (10), a method of controlling the actual pressure inside a cabin (50) and an outflow valve (14; 15; 16; 17), especially for use in said system (10) or said method. The invention provides communication of actual cabin pressure to the outflow valve (14; 15; 16; 17) and additionally a common data exchange line (22) connecting the components of the cabin pressure control system (10). The system (10) is highly redundant and reliable, guarantees the desired sophisticated pressure control even if one or several components fail and allows complete elimination of the previously used fully pneumatic safety valves.
