INJECTOR WITH DOUBLE CONICAL SWIRLER Russian patent published in 2018 - IPC B05B1/34 

FIELD: machine engineering.

SUBSTANCE: injector comprises a cylindrical hollow body with a channel for supplying liquid, in which a sprayer is fixed consisting of three throttling elements. The sprayer is in the form of oppositely located vertices and axially symmetrical hollow conical swirlers: the upper and the lower ones. The lower swirler conical shell is fixed by means of at least three spokes fixed in its upper part by one end on the lower swirler conical shell, and its other end it is fixed in the circular groove of injector channel made on its inner surface. The conical surface vertex of the upper swirler conical shell is fixed on a round perforated plate installed in the circular groove of the injector channel and resting on the lower swirler vertex. There are through helical cuts made on the outer surfaces of hollow conical swirlers. The throttling effect of the sprayer is determined as a by total throughput capacity of constituent elements thereof, wherein the total throughput capacity of the upper swirler and the perforated plate is higher than that of the lower swirler.

EFFECT: increased spraying efficiency, simplified structure and reduced material consumption.
