Zusammenfassung:FIELD: devices for spraying different liquids, possibly liquid fuels in power engineering, chemical, metallurgical industry branches. SUBSTANCE: acoustic nozzle has housing with outlet jet and with annular resonator on end wall. Fuel sprayer is arranged along axis of said nozzle. According to invention nozzle unit in the form of polyhedron is mounted on fuel sprayer; said polyhedron forms with inner surface of housing annular row of inlet contraction slits gradually passing at forming restriction to diffuser slits provided with calibration protrusion having in cross section segmental jets. One part of diffuser slits with calibration protrusion are in planes normal relative to normal line inclined to axis; second part of diffuser slits are inclined relative to tangent plane in tangential direction. EFFECT: enhanced quality of spraying, improved intensity of combustion of liquid fuel. 4 cl, 2 dwg
