SPRAYER Russian patent published in 2012 - IPC A62C31/02 

FIELD: process engineering.

SUBSTANCE: sprayer hollow cylindrical case consists of cylindrical part with outer thread for connection to fluid union, taper adapter part and cylindrical part with larger diametral section and inner threaded surface to receive nozzle aligned with said case and made up of cylindrical surface with outer thread for interaction with said case that changes into taper surface to be terminated in blind web with jet at its centre, axially symmetric with the nozzle and made up of serial cylindrical and taper restricting holes. Taper hole larger diametre is located on nozzle blind web. Case and nozzle make three aligned inner and outer chambers. 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. Paired channels are arranged at right angle in the case lengthwise planes while conical lateral surface features apex angle equal to 90°. Screen sprayer is arranged in expansion chamber, perpendicular to its axis.

EFFECT: higher efficiency of spraying.
