VENTILATING AIR INTAKE ARRANGEMENT WITH MOBILE CLOSING DEVICE

摘要

The invention concerns a ventilating air intake arrangement with mobile sealing device. The arrangement comprises at least one air passage channel (12) with an air vent (14), and is designed to ventilate at least one confined zone (11) in an aircraft with fresh air entering upstream, through the air vent, in the channel and exiting downstream thereof towards the zone to be ventilated. The invention is characterized in that the cross-section of the air passage channel (12) is automatically adjustable based on the speed and the altitude of the aircraft and the arrangement comprises therefor controllable mobile-element closing means (17) associated with the channel and for varying its cross-section.
