NOZZLE Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for spraying of 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 by the fact that in the liquids spraying nozzle containing a hollow housing with a nozzle and a central core, housing is made with fluid supply channel and contains coaxial, rigidly coupled with housing bushing with nozzle secured at its lower part, made in form of cylindrical two-stage bushing, which upper cylindrical stage is connected with central cylindrical core by means of threaded connection, having through internal central hole, and installed with annular clearance relative to cylindrical bushing inner surface, and the annular gap is connected, at least to three radial channels, made in a two-stage bushing, connecting it to annular cavity, formed by bushing inner surface and upper cylindrical stage outer surface, wherein the annular cavity is connected to the housing fluid supply channel, wherein in central cylindrical core lower part hollow cone swirler is attached, which conical shell is fixed by means of at least three spokes, in its upper part fixed on swirler conical shell by one end, and by other end is in the annular groove, made on the central cylindrical core inner surface, at that, on the hollow cone swirler outer surface helical thread is made.

EFFECT: technical result is increase of fine spraying efficiency.
