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.
L'invention concerne un système de commande de la pression de cabine (10), un procédé de commande de la pression réelle à l'intérieur d'une cabine (50) et une vanne de régulation échappement cabine (14; 15; 16; 17), s'utilisant notamment dans un tel système (10) ou procédé. L'invention permet de communiquer la pression de cabine réelle à la vanne de régulation échappement (14; 15; 16; 17) et comprend une ligne d'échange de données communes supplémentaire (22) reliant les composants du système de commande de pression de cabine (10). Le système (10) est très redondant et très fiable, et garantit la commande de pression perfectionnée souhaitée même si un ou plusieurs composants tombent en panne et permettent la suppression totale des vannes de sûreté entièrement pneumatiques antérieurement utilisées.
