INJECTOR FOR SPRAYING LIQUIDS Russian patent published in 2017 - IPC A62C31/02 

FIELD: machine engineering.

SUBSTANCE: in an injector for spraying liquids, comprising a hollow body with a nozzle and a central core, the body is provided with a channel to supply liquid and contains a coaxial bushing rigidly connected to the body, the bushing has a nozzle fixed in its lower part, made in the form of a cylindrical two-stage bushing, the upper cylindrical stage of which is connected by means of a threaded joint with a central cylindrical core having a through internal central hole, and installed with an annular gap relative to the internal surface of the cylindrical bushing, and the annular gap is connected with at least three radial channels made in two-stage bushing, which connect it with an annular cavity formed by inner surface of the bushing and outer surface of upper cylindrical stage. The annular cavity is connected to the channel of the body for supplying liquid. In the bottom part of the central cylindrical core the hollow conical swirler is fixed, the conical shell of which is fixed by means of at least three spokes, fixed at one end to a swirler conical shell, in its upper part, and at the other end - in the ring groove, formed on the inner surface of the central cylindrical core. The screw thread is cut on the outer surface of the hollow conical swirler.

EFFECT: fine-dispersed liquid sprayer efficiency increase.
