FIELD: valving. SUBSTANCE: each inlet made in the rotor is in communication with nozzles through inclined and parallel radial passages. The nozzles are arranged on the arms of the rotor. Branch pipes are received partially, e. g., in the inlets, and each two inclined passages coupled with one inlet is symmetrical with respect to the inlet and has inclination of 120-150 deg to its axis and diameters of 0.6-1.0 of the inlet diameter. The ratio of the diameter of the branch pipes to the diameter of the inlets is equal to 1.5-2.5. The ratio of the diameter of end sections of the nozzles to the diameter of critical sections is equal to 1.2-2.0. The ratio of arm radii of the rotor to the diameters of the passages is equal to 5-15, and the ratio of diameter of the passages to the diameter of the critical section is equal to 1.2-2.0. The side walls are streamlined and symmetrical with respect to the vertical planes. EFFECT: improved design. 5 cl, 5 dwg
