FLUID SPRAYER Russian patent published in 2011 - IPC A62C31/02 B05B1/02 

FIELD: process engineering.

SUBSTANCE: invention may be used in fire fighting equipment, agriculture, etc. Hollow cylindrical sprayer casing has outer thread for distributing pipeline to be connected thereto for feed fluid and inner thread to connection to taper nozzle. Casing and nozzle form two aligned chambers. Note here that cylindrical chamber serves to feed fluid while said taper chamber makes higher-pressure chamber. Jet made up of cylindrical throttling orifice and taper orifice is arranged on nozzle side opposite fluid feed side. Note here that taper orifice surface is provided with angular thread. Nozzle tape side surface has at least two lines of cylindrical throttling orifices with their axes perpendicular to nozzle side surface. Every line has at least three cylindrical throttling orifices. Note that, in horizontal plane orifice axis projections are spaced apart for angle of 7.5 - 60°.

EFFECT: higher efficiency of spraying.
