KOCHETOV'S PNEUMATIC SPRAYER Russian patent published in 2013 - IPC B05B7/10 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in fire fighting, agriculture, etc. Sprayer casing represents upturned barrel with its bottom provided with threaded hole to receive central cylindrical insert to be arranged axially symmetric with said casing, said insert having central axial channel of jet-directing device to feed fluid to be sprayed. At least, one opening to feed air or gas at pressure is arranged in casing side surface perpendicular to its axis. Said opening is communicated with annular chamber formed by outer surface of aforesaid central cylindrical insert and casing inner surface. Cylindrical sleeve of jet-directing device to feed fluid to be sprayed via annular clearance is secured to casing inner side surface, said clearance being formed by outer surface of said insert and sleeve outer surface. Annular clearance communicates with annular chamber. Fluid flow swirling chamber and diffuser are arranged aligned inside central cylindrical insert, on its inner surface. Plane of diffuser edge is aligned with that of annular clearance at outlet of jet-directing device to feed fluid to be sprayed.

EFFECT: higher efficiency of spraying.
