DEVICE FOR LIQUID SPRAYING Russian patent published in 2020 - IPC B05B1/34 

FIELD: liquid atomization or spraying devices.

SUBSTANCE: invention relates to a liquid spraying device, comprising a housing with an inner chamber and a perpendicular working fluid supply pipe, a nozzle with a central outlet opening, and a coaxial core in form of a swirler with a screw groove on the outer cylindrical surface inserted into the nozzle, wherein nozzle opening is equipped with truncated cone expanding outward. Device is characterized by that core is inserted and fixed in nozzle at distance of 1/2 - 5/6 of core length, wherein the nozzle is inserted into the housing chamber, and the branch pipe is interconnected with the chamber by the narrowing channel, which guides partially or completely the working fluid flow to the core end protruding from the nozzle.

EFFECT: device allows spraying liquids with viscosity of up to 140 mPa⋅s due to exclusion of transition between camera and screw samples in form of step, broader functional capabilities due to possibility of spraying working fluid on walls inside pipes and narrow reservoirs due to compactness, at that, providing stable spraying quality during entire operation due to fixation of core in nozzle.
