COMPOSITE INJECTOR FOR LIQUID SPRAYING Russian patent published in 2018 - IPC B05B1/26 B05B1/34 

FIELD: technological processes.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. Composite injector for liquid spraying contains a hollow body with a nozzle and a central core. Body is provided with a channel for supplying liquid and comprises a coaxial, rigidly connected bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage bushing. Upper cylindrical step of the sleeve is connected by means of a threaded connection to a coaxial central core coaxial with it having a central hole and installed with an annular gap with respect to the inner surface of the cylindrical sleeve. To the central core rigidly connected to the upper cylindrical stage of the two-stage nozzle sleeve, an external solid diffuser is coaxially attached, 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 overlapped.

EFFECT: high efficiency of liquid atomizing.
