PAINT SUPPLYING CARTRIDGE UNDER PRESSURE INCLUDING SUPPLEMENTARY BAG AND LOWER AIR INLET ORIFICE Russian patent published in 2011 - IPC B05B7/24 

FIELD: machine building.

SUBSTANCE: container of assembly is used for supply of liquid. It consists of at least one side wall, bottom and the first set of mechanical components engaging the second set of mechanical components. Additionally, the container includes an auxiliary case or auxiliary assembly collar for supply of liquid and a device for supply of air within boundaries of at least one side wall of the container near its bottom. Also, the container has multitude of ribs for reliable distribution of air passing along upper surface of the container bottom. The container can be equipped with at least one pressure release valve preventing fluid medium flow from the assembly for liquid supply when pressure in the system is beneath the threshold value. The container includes at least one pressure release valve opening liquid medium flow from the assembly for liquid supply when pressure exceeds or equal to a threshold value. The assembly for supply of liquid consists of the container, of a soft supplementary bag, of the auxiliary case and auxiliary collar together creating a force-pump unit.

EFFECT: facilitating maximal efficiency in spraying or sprinkling devices applicable in systems of high pressure supply of liquid.
