Abstract (en)
[origin: EP0337375A1] Air-extraction device for conditioning the atmosphere of a railway vehicle and for temporarily pressurising this atmosphere. It comprises at least one axial fan (1) with blades (10) which can move in rotation about radial axes of its wheel between a first position in which they extract the air from the atmosphere of the carriage, and a second position in which they force the outside air back into the carriage, and means for switching these blades, in operation, from one of these positions to the other. <IMAGE>
