PNEUMATIC NOZZLE Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. This is achieved in that in a pneumatic nozzle for spraying liquids containing a hollow body with a nozzle and a central core, housing is made with fluid supply channel and contains coaxial, rigidly coupled with it bushing with nozzle secured at its lower part, made in form of cylindrical two-stage bushing, the upper cylindrical stage of which is connected by means of a threaded connection to the central core coaxial with it, having a central opening and installed with an annular gap with respect to the inner surface of the cylindrical sleeve, wherein the annular gap is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the bushing inner surface and the upper cylindrical stage outer surface, wherein the annular cavity is connected to the channel of the housing for supplying liquid, to the central core, in its lower part, a diffuser is rigidly attached, made in the form of a truncated cone coaxial with the central hole of the core, and attached by its upper base to the base of the cylinder of the central core, and a cutter is attached to the lower base of the truncated cone by means of at least three spokes, which is made in the form of an end circular plate whose edges are bent towards the annular gap, and on the outer side surface of the truncated cone there are screw grooves.

EFFECT: high efficiency of liquid atomizing.
