LIQUID FLOW EJECTOR-TYPE SPREADER Russian patent published in 2017 - IPC A62C31/02 

FIELD: machine engineering.

SUBSTANCE: ejection type liquid flow distributor for the nozzle is provided; it comprises a hollow body consisting of a cylindrical part with an external thread for connection to the nozzle distribution manifold and secured in the lower portion of the housing union nut with a liquid flow divider. In the body, coaxial to it, a cylindrical hole is made, in the upper part of which a screen filter is installed. At the bottom - with throttle orifice plate. To the end surface of the union nut axially symmetric to the body, a fluid flow divider is attached, which consists of coaxial, coaxially located pyramidal shells in the form of generating grids: external, intermediate and internal. Each of the shells comprises a wire frame from two bases of square shape and lateral edges of a truncated pyramidal surface. The outer shell is fixed to the casing by the bigger base. The second smaller base is simultaneously a large base of the intermediate shell with lateral ribs, and its smaller base is simultaneously a large base of the inner shell with a smaller base. The generating grids in the form of truncated pyramidal surfaces are arranged so that all their vertices lay on the axis coinciding with the casing axis. The direction of the external and internal vertices of generating meshes coincide, and generating an intermediate mesh vertex directed opposite vertices of generating outer and inner meshes.

EFFECT: fine-dispersed liquid sprayer efficiency increase.
