SPRAYING NOZZLE Russian patent published in 2008 - IPC B05B1/18 

FIELD: engines and pumps.

SUBSTANCE: spraying nozzle contains a case fixed on the water supply pipe and provided with a deflector arranged on its side surface. The deflector is arranged along the helical line. The case accommodates a screw-type flow guider, the guider coil diameter decreasing along the helical generatrix with the angle of taper varying from 25 to 30°. Before every turn of the deflector, the case side wall has the holes the number of which is determined from the expression where q_n is the nozzle flow rate, μ is the flow rate factor (for thin wall holes μ=0.6÷0.62), ω is the hole actual section area, g is the free fall acceleration, H is the head in the nozzle.

EFFECT: higher reliability and fine-disperse spraying.
