FIELD: power engineering industry. SUBSTANCE: side surface of power separation chamber (at distance within one-fourth and three-fourth of its length) is provided with through holes 8. Sound gas-dynamics resonator 3 is connected to pipe connection for incoming compressed flow and communicated with nozzle head 4 through cavity 2 enveloping power separation chamber; resonator itself is located in this chamber. Besides, if more than one resonating cavity is available, cavities are furnished with pistons, limiting length of at least one of cavities within 2-4 its diameters and of at least another one within 5-8 its diameters. At same time, holes 8 in side surface of power separation chamber, arranged closer to nozzle head 4, have diameters within 0.01-0.03 of chamber diameter but not in excess of 0.5 mm, and holes 8 located closer to throttle valve 7 have diameters 1.5-2.0 times greater, with total area of all holes 8 amounting to 0.05-0.1 of minimum passage area of nozzle head 4. EFFECT: enhanced reliability of operation. 2 cl, 2 dwg
