FIELD: power engineering.
SUBSTANCE: invention relates to vortex turbines which can be used as a drive for pumps, compressors, electric power generators, including at gas distribution stations, as backup power sources. Multi-flow vortex turbine comprises housing (1), in which rotor (2) with blades (4) along periphery is located on the shaft. Rotor (2) is interconnected with power transmission shaft equipped with magnetic coupling. Housing (1) together with rotor (2) forms annular channel (6), in which there are at least two main nozzles for supplying gas directly to blades (4) of rotor (2) and outlet channels with cutoffs located in front of them. In housing (1) between outlet channels with cutoffs there is at least one additional nozzle, sections of which are located flush with external generatrix of annular channel.
EFFECT: invention is aimed at increasing the efficiency of the vortex turbine due to efficient use of the flow section in the circumferential direction and reducing hydraulic losses.
