SPRAYER WITH BUILT-IN PRESSURE CHANNEL Russian patent published in 2017 - IPC B05B7/06 B05B7/08 B05B7/24 

FIELD: machine building.

SUBSTANCE: invention relates to sprayers and can be used in many industries. Detachable barrel (20), adapted for use with sprayer (2), includes hydraulic adapter adapted for connection of barrel (20) with coating material container (80). Hydraulic adapter has channel for liquid and accelerating delivery opening (56). Detachable barrel (20) also includes sprayer (2) adapter, adapted for connection of barrel (20) with sprayer (2) base, having accelerating supply opening (44). Besides, barrel includes accelerating channel (48), hydraulically connecting accelerating supply opening (44) with accelerating delivery opening (56) and hydraulically connected with accelerating channel (48), which is barrel (20) integral part and which includes neither sleeve, nor external liquid pipeline. Barrel (20) also includes liquid nozzle opening, through which coating material can leave barrel (20), hydraulically connected with liquid channel through channel, formed in barrel (20). Accelerating channel (48) is adapted to supply accelerating liquid under pressure from sprayer (2) into accelerating delivery opening (56) to ensure sputtered coating material supply acceleration from compatible coating material container (80) for spraying by means of sprayer (2). Accelerating channel (48) is also adapted to supply liquid coating material under pressure from compatible coating material container (80) through liquid nozzle to spray liquid by means of sprayer (2). Assembly consists of detachable barrel (2) and coating material container (80). Coating material container (80) is adapted for connection with sprayer (2) compatible barrel (20).

EFFECT: group of inventions technical result is improved removal of coating materials from container for application with help of solvent.
