    In a regenerative rotodynamic machine, a portion of a disc-like impeller (11) adjacent the impeller periphery extends radially through an annular chamber (13) in the machine casing concentric with the impeller, thereby dividing said chamber into two annular side channels (13A, 13B) one on each side of the impeller. The portion of the impeller lying in the annular chamber has scooped out annular cavities or recesses in its sides in which are disposed rings of aerodynamic blades (18A, 18B) and fluid flow passing around the annular chamber from an inlet to an outlet is caused to circulate repeatedly, flowing radially outward through the blading in the impeller cavities and radially inward in the annular side channels alongside the impeller outside the impeller cavities. Shroud rings (16A, 16B) at the blade tips form cores around which this circulation takes place. The blades are cast intagrally with the impeller disc or with the shroud rings. The aerodynamic blades are designed so that the angle between the entry and exit flows of each blade is greater than 90 DEG .

    The invention relates to the field of compressor engineering, in particular, to vortex centrifugal machines. The aim of the invention is to increase productivity. Fig. 1 schematically shows a vortex centrifugal machine, a longitudinal section; Fig. 2 shows the inner side of the left end surface of the housing J in Fig. 3, the same right end face of the housing; in Fig.4 the impeller of the machine; on fig.Z section aa in figure 4; figure 6 - section bb in figure 4; figure 7 - profile of the aerodynamic blades of the impeller; FIG. 8 is a diagram of pellet flow velocity vectors) in FIG. 9, a machine with two impellers, a longitudinal section; Fig. 10 shows a variation of a machine with a three-crown vane impeller. The vortex centrifugal machine includes a housing 1 with an annular chamber 2 formed by depressions 3 in its end walls 4 and 5 and, with inlet and outlet nozzles 6 and 7, and also an interceptor 8 located between the latter and the impeller 9 mounted to the shaft 9 The ends of the working aerodynamic blades I1 of which are interconnected by a screen ring 12, Wheel 10 divides the annular chamber 2 into two concentric 11 annular cavities with respect to the rim of the elbows 11, of which, together with the screen ring 12, has a D-shaped radial section form. The blades 11 are located in the annular chamber 2 with an axial clearance 6, the annular cavity is made in the form of a bucket-shaped recess I3 on one of the side surfaces 14 of the disk 15 of the impeller 10, while the radial extent of the recess 13 in the disk is greater than the radial length of the blades 11. Blades I1 are cast in one piece with the disk 15, and the screen ring 12 is fixed at the ends of the blades 11. The disk 15 has a second crown of blades P. located on its opposite side.
