Abstract
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.
