Abstract

Système de ventilateur d'aération, comprenant un ventilateur 1 à écoulement axial et à ailettes radiales 3 monté sur un axe vertical, une première paroi fixe 6, de révolution autour de l'axe vertical du ventilateur 1, à sections droites croissantes à partir dudit ventilateur 1, formant la paroi interne d'une chambre de diffusion 10 pour l'air aspiré par le ventilateur 1, une seconde paroi fixe 8, de révolution autour du même axe, qui comprend une partie inférieure conique 8b, au-dessous du ventilateur, et une partie supérieure 8a au-dessus du ventilateur, à sections croissantes à partir dudit ventilateur. La chambre de diffusion 10 a la forme annulaire d'un diffuseur de turbine hydraulique et est courbée vers l'extérieur par rapport à l'axe du ventilateur. Un tel système, plus spécialement destiné à l'aspiration de l'air dans les tunnels pour chemins de fer, est de dimensions plus réduites que celles des systèmes classiques.
