ACOUSTIC SPRAYER Russian patent published in 2011 - IPC B01J2/02 

FIELD: machine building.

SUBSTANCE: acoustic sprayer of low viscous liquids consists of case (1) with perforated bottom (3), of branch for input (2) of liquid product into case and of source of acoustic oscillations in form of nozzle (4) and flexible element (5). The source of acoustic oscillations is equipped with an adaptive system for changing its working parametres depending on liquid consumption rate; the system includes at least one bend (6) from the input branch; piston (7) and spring mechanism (8) are arranged in the bend; spring mechanism (8) connects the bend with the piston; the system further includes guiding profile (14) and carriage (9). The carriage consists of a frame, of at least four rollers and the spring mechanism; also, at least one roller (11) of the carriage contacts the piston, while another one (13) contacts the guiding profile, and two rollers (12) contact the flexible element. The side of the guiding profile contacting the roller has curvilinear surface.

EFFECT: extended range of consumption rate at dispersing liquid of low viscosity facilitating formation of drops of uniform dimension.
