INTEGRATED NOZZLE Russian patent published in 2018 - IPC B05B1/00 

FIELD: devices for liquid spraying or atomizing.

SUBSTANCE: invention relates to fluid spraying equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. It is achieved by the fact that in a complex nozzle for spraying liquids containing a hollow nozzle 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, a divider is provided that is made in the form of an end circular plate whose edges are bent towards the annular gap, and screw grooves are provided on the outer lateral surface of the truncated cone, and an outer continuous diffuser is coaxially attached to the central core rigidly connected to the upper cylindrical stage of the two-stage nozzle sleeve, so that the exit section of the annular gap connected to at least three radial channels made in the two-stage nozzle sleeve is not blocked.

EFFECT: high efficiency of liquid atomizing.
