FIELD: devices for liquid atomization or spraying.SUBSTANCE: invention relates to equipment for liquid atomization and can be used in fire fighting, agriculture, chemical industry and heat power engineering. Pneumatic nozzle for spraying liquids contains a hollow body with a nozzle and a central core. Body is made with a channel for supplying liquid and contains a coaxially rigidly connected bushing with a nozzle fixed in its lower part. Nozzle is made in the form of a cylindrical two-stage bushing. Upper cylindrical stage is connected by means of a threaded connection to a coaxially aligned central core. Core has a central hole and is mounted with an annular gap with respect to the inner surface of the cylindrical sleeve. Annular gap is connected to at least three radial channels made in a two-stage bushing. Annular cavity is connected to the channel of the housing for supplying liquid, to the central core. Sprayer is rigidly attached to its lower part. Atomizer is made in the form of a truncated cone coaxia
