Abstract (en)
The extractor consists of coaxial upper (2) and lower (3) members separated by spacers (4) and with the lower member mounted on the upper end of a duct (7). The base (11) of the upper member has an axial cavity (25) containing a centrifugal turbine comprising a motor with a stator (23) and rotor (26) and one or more blades (24), the lower edges (27) of which lie flush with the bottom of the cavity.
Abstract (fr)
L'invention concerne un dispositif (1) mixte, statique/dynamique pour l'évacuation de fluide gazeux, comprenant d'une part un élément supérieur (2) et d'autre part un élément inférieur (3), superposés, coaxiaux, rigidement fixés l'un à l'autre par des entretoises (4) de liaison. Le dispositif (1) comporte de plus une cavité axiale 25) ouverte vers un espace (8) abritant les pales (24) d'une turbine centrifuge à rotor (26) et stator (23) localisés dans la cavité axiale (25). <IMAGE>
