LIQUID DOSING DEVICE Russian patent published in 2015 - IPC G01F11/04 

FIELD: transport; distribution.

SUBSTANCE: invention relates to liquid dosing equipment and can be used for multiple dosing of controlled amounts of liquid. Essence of the invention: liquid dosing device (1) includes elastically compressed container (2); cover plate (3) functionally connected to container (2); dosing chamber (4) functionally connected to cover plate (3). With that, cover plate (3) includes a nozzle, at the top of which there is an outlet opening. Dosing chamber (4) includes a base with an outlet opening, side walls and at least one inlet opening. Proximally to the outlet opening of dosing chamber (4) there located is at least one regulating opening. A plunger is located in dosing chamber (4). The plunger has a possibility of being moved relative to dosing chamber (4), as a result, it is moved to a locking position at compression of container (2). Element (6) intended for retention of valve (7) is located below the base of dosing chamber (4). Valve (7) located in element (6) has a possibility of being moved between an open position at which a liquid flow is possible through the outlet opening and a closed position in which valve (7) shuts off the outlet opening.

EFFECT: dosing of liquid in constant amount, on which no pressure fluctuations have an effect, which are caused by variability of a compressive force and filling level of a container.
