WIDE-FLAME CENTRIFUGAL NOZZLE Russian patent published in 2017 - IPC B05B1/34 

FIELD: machine engineering.

SUBSTANCE: in the wide-flame centrifugal nozzle to the bottom of a cylindrical cup of a swirl chamber at the side of the nozzle insert there is an auger with screw blades axially symmetricaly and coaxially fixed thereon. The direction of the helical blades is opposite to the flow twisting direction in the swirl chamber or coincides with the twisting flow direction in the swirl chamber. The helical blades of the auger are located thereon with increase of their outer diameter away from the bottom of the cylindrical cup and inscribed in the cone surface restricting thereof.

EFFECT: increased spraying efficiency.
