SPRAYER WITH MATCHED FLUID AND OPERATING GAS FLOW RATES Russian patent published in 2009 - IPC B05B7/08 

FIELD: engines and pumps.

SUBSTANCE: sprayer with matched fluid and operating gas flow rates incorporates casing with through hole, its axis being parallel to the axis of symmetry of round casing. The said through hole communicates with fluid feed hole made in the round casing wall and with one or more fluid feed lengthwise channels arranged around the said through hole axis. Note that the through hole is enveloped from outside by operating gas manifold chamber that communicates with the aforesaid operating gas feed hole made in the round casing wall and with one or more operating feed lengthwise channels arranged around the axis of symmetry of the round casing. The through hole houses taper-surface slide valve interacting with its spring and slides. One end face of each slide is coupled with the slide valve tapered surface, while its other end interacts with slide spring. The slides are arranged in their appropriate holes communicating the round casing through hole with operating gas feed lengthwise channels. The slide hole axes are perpendicular to the through hole axis. The slides can block the operating gas feed channels. The through hole and fluid feed lengthwise channels communicate via radial holes with their axes perpendicular to that of the through hole. Every radial hole accommodates body interacting with the spring to block the fluid feed lengthwise channels.

EFFECT: equally dispersed drops on varying fluid flow rate by matching fluid and gas flow rates.
