PNEUMATIC NOZZLE WITH TWO-PHASE FLOW OF SPRAY Russian patent published in 2018 - IPC A62C31/02 

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. In a pneumatic nozzle for spraying liquids containing a hollow body with a nozzle and a central core, the housing is provided with a channel for liquid supplying and contains a coaxial, rigidly coupled with housing bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage, which upper cylindrical stage is connected coaxial with it central cylindrical core by means of threaded connection, having a central hole and installed with annular gap relative to cylindrical bushing inner surface, 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 annular cavity is connected with housing fluid supply channel, to a central core, in its lower part, a nozzle rigidly attached 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 to the lower base of the truncated cone by means of at least three spokes, divider is provided 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: higher efficiency of liquid atomization.
