Abstract (en)
[origin: US4776757A] The turbine comprises orientable vanes or flaps (10b, 10a) respectively forming the distributor and a movable part of the volute of the turbine. These vanes are disposed in such manner that (a) the intrados (15) of one thereof directs the fluid which travels thereover in a path which is no longer in contact with the other, (b) the extrados (14b) of one of the vanes is travelled over by a fluid current which feeds the other vane and (c) the extrados (14a) of the other of the vanes is travelled over by a fluid current entering directly into the turbine only between its shaft (11a) and its trailing edge (13a). The turbine has application in the supercharging of engines of motor vehicles.
Abstract (fr)
L'invention concerne les turbines de turbocompresseur. La turbine comprend des aubes ou volets (10b, 10a) orientables formant respectivement le distributeur et une partie mobile de la volute. Ces aubes sont disposées de manière que (a) l'intrados (15) de l'une d'elles dirige le fluide qui le parcourt sur une trajectoire qui n'est plus jamais en contact avec l'autre, que (b) l'extrados (14b) de l'une des aubes soit parcouru par un courant de fluide qui alimente l'autre aube et que (c) l'extrados (14a) de l'autre des aubes ne soit parcouru par un courant de fluide entrant directement dans la turbine qu'entre son axe (11a) et son bord de fuite (13a). Application à la suralimentation des moteurs des véhicules automobiles.
