DEVICE FOR SUPPLY OF WORKING FLUID MEDIUM Russian patent published in 2018 - IPC F16N7/30 

FIELD: manufacturing technology.

SUBSTANCE: device is intended for feeding into the deaf cavities of the mechanisms and systems of a given amount of different liquids. Device comprises a housing with an inlet nozzle for supplying the working gas and an outlet nozzle for outputting a fluid working medium. Inside the case there are: chamber of elastic material in the form of a glass, with the open side facing the outlet nozzle and connected to the case at about half the height of the internal cavity of the case, collector output fluid working environment and the sealing element installed in the outlet nozzle. In the case from the bottom of the chamber, a through hole is made of an elastic material, in which an additional sealing element is installed, isolating the internal cavity of the device from the environment. Additional sealing element is installed so that a pneumatic connection is possible when the device of its internal cavity acts with the environment due to the mechanical connection of the additional sealing element with the bottom of the chamber.

EFFECT: technical result is to increase the reliability of the device in all conditions of its operation.
