Abstract
Centrifugal turbine, perfected, characterized by being constituted by a succession of stamped metal plate pieces, equal to each other and endowed with an elongated general shape, each of which has a wide rectilinear central area, provided with a cross section suitable for constituting one of the blades of the impeller, and two extreme fins, arranged to be located next to the other parts that make up that one, with which they are properly aligned, defining an ideal cylindrical surface and being able to allow fixing, by beading set, of two pieces of circular plant, also obtained from stamped metal plate, which constitute the heads of the set.
