SPRAYER Russian patent published in 2011 - IPC A62C31/02 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in fire fighting, agriculture, etc. Proposed sprayer comprises hollow cylindrical case communicated with nozzle accommodating jets arranged in mutually perpendicular planes. Note here that said hollow case consisting of cylindrical part with outer thread for jointing to distributing pipeline union and two hollow tapered cylinder belts aligned therewith, and nozzle arranged at case bottom and formed by outer taper surface and blank face web arranged perpendicular to nozzle axis and provided with central throttling hole and, at least, three holes inclined to nozzle axis at 45°. Note also the cylindrical flange is made on nozzle taper surface and provided with outer thread for jointing nozzle with case bottom tapered cylinder belt. Note that extra line of jets is arranged on side opposite fluid feed side. Said jets are formed by, at least, three pairs of mutually perpendicular vertical fluid passages and horizontal passages to cross on nozzle conical lateral surface to form jets outlets. Note that paired channels are arranged at right angle in the case lengthwise planes. Note also that nozzle lateral conical surface has apex angle equal to 90°, while tapered cylinder belt rigidly jointed to the case has two lines of throttling holes: one line represents, at least, three horizontal holes made on cylindrical surface, while another line is made up of, at least, three inclined holes at 45° made on conical surface. Note that projections of hole axes in said lines are spaced apart by angle varying from 7.5° to 60°.

EFFECT: higher efficiency of spraying.
