Abstract

L'invention concerne des perfectionnements aux systèmes de commande de la mise en pression de cabines d'avions. Système comprenant deux dispositifs de commande, chacun présentant un état activé et un état désactivé et étant agencé de manière, lorsqu'il est activé, à commander la pression dans la cabine, et comportant également des moyens agencés pour activer ou désactiver les dispositifs de commande en fonction de conditions prédéterminées de telle manière que dans des conditions de fonctionnement normales l'un des deux dispositifs seulement est activé. Applications à la pressurisation des cabines d'avions.The invention relates to improvements to systems for controlling the pressurization of aircraft cabins. System comprising two control devices, each having an activated state and a deactivated state and being arranged so, when activated, to control the pressure in the cabin, and also comprising means arranged to activate or deactivate the control devices according to predetermined conditions such that under normal operating conditions only one of the two devices is activated. Applications to the pressurization of aircraft cabins.
