PNEUMATIC INJECTOR Russian patent published in 2017 - IPC A62C31/02 

Abstract RU 2636889 C1

FIELD: fire safety.

SUBSTANCE: in pneumatic injector for spraying liquids, containing a hollow body with a nozzle and a central core, the body is made with fluid feed channel and includes the axial, rigidly coupled therewith sleeve with nozzle fixed in its lower part, made in the form of two-step cylindrical sleeve, whose top cylindrical step is connected by means of the thread joint with the coaxial with it central core having central hole and installed with annular gap relatively to the internal surface of the cylindrical sleeve, wherein annular gap is connected with at least three radial channels made in the two-step sleeve connecting it's with the ring cavity created by the internal surface of the sleeved and external surface of the top cylindrical step, wherein that ring cavity is connected with the casing channel for liquid supply, the sprayer is rigidly fixed to the central core in its bottom part, made as truncated cone coaxial to the central hole of the core, and fixed by its top base to the base of the central core cylinder, and the sprayer is fixed to the bottom base of truncated cone by means of at least three spikes, which is made in form of the end round plate, whose edges are bent towards the annular gap, and on the external side surface of the truncated cone there are helical grooves.

EFFECT: fine-dispersed liquid sprayer efficiency increase.
