LIQUID SPRAYING APPARATUS Russian patent published in 2000 - IPC

FIELD: agriculture, may be used in different branches of industry. SUBSTANCE: liquid spraying apparatus has casing with inner chamber communicated with inner cavity of cap via at least two bores uniformly distributed along circumferential portion of core and inclined with respect to outer cylindrical surface of core. Each bore has cross-section configured as incomplete segments with chords equally spaced from core axis, with space exceeding radius of central opening of nozzle, or configured as circular sectors with radius of inner arcs of circle exceeding radius of central opening of nozzle. Spraying apparatus of such construction allows liquid spray cone angle to be regulated. Spraying apparatus may be used in agriculture, as well as in other branches of industry, for instance, in car washing stations, in fire or spark extinguishing equipment for creating protective water curtains, ornamental fountains, shower mixers etc. EFFECT: increased efficiency, wider range of usages and reduced losses of vortex flow energy resulting in increased spraying area.
