NOZZLE WITH ADDITIONAL SPRAYER Russian patent published in 2018 - IPC A62C31/00 

FIELD: devices for liquid spattering or spraying.

SUBSTANCE: invention relates to equipment for spraying of fluids and can be used in fire fighting, agriculture, chemical industry and heat power engineering. This is achieved by the fact that in the nozzle with an additional sprayer, which contains a hollow body with a nozzle and a central core, the body is performed with a channel for supplying liquid and comprises a coaxial, rigidly connected with the body sleeve with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage bushing, the upper cylindrical stage of which is connected by means of a threaded connection to a central cylindrical core that has a through inner central opening and to the installed annular gap relative to the cylindrical bushing inner surface, and 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 inner surface of the bushing and the outer surface of the upper cylindrical stage, wherein the annular cavity is connected with a housing fluid supply channel, where in the lower part of the central cylindrical core, a hollow conical swirler is fixed, the conical shell of which is fixed by means of at least three spokes, which are fixed with one end on the conical shell of the swirler in its upper part, and with the other end in a circumferential groove formed on the inner surface of the central cylindrical core, while a helical thread is made on the outer surface of the hollow conical swirler.

EFFECT: high efficiency of liquid atomizing.
