FLUID 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. Fluid sprayer comprises hollow cylindrical case communicated with nozzle with jets arranged in mutually perpendicular planes. Note that said hollow case consists consisting of cylindrical part with outer thread for jointing to distributing pipeline union, conical adapter part and cylindrical part with larger cross section and inner threaded surface. Nozzle formed by cylindrical surface with outer thread is secured at case bottom to interact with case cylindrical part. Note that nozzle cylindrical surface changes into conical surface to end in face dead web perpendicular to case axis and furnished with jet arranged in web center and made up of cylindrical and intercommunicated conical throttling holes. Note also that larger diametre of conical hole is located on nozzle dead web. Note case and nozzle form three aligned inner cylindrical chambers. Note also 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. Paired channels are arranged at right angle in the case lengthwise planes while conical lateral surface features apex angle equal to 90°.

EFFECT: higher efficiency of spraying.
