DEVICE FOR FLUID MEDIUM SUPPLY Russian patent published in 2020 - IPC F16N7/30 

FIELD: machine building.

SUBSTANCE: device relates to hydraulic transport using gas pressure. Device comprises a pyrotechnic generator with a gas-generating charge, an actuation system and a working gas discharge pipe, vessel with cavity for fluid working medium, inlet branch pipe for working gas and outlet branch pipe for fluid working medium, arranged in cavity for fluid working medium is chamber from elastic material in form of barrel, open side facing outlet pipe and connected to vessel housing, a heating element for a fluid working medium installed in a reservoir with the possibility of insulation of a fluid working medium from a heat carrier. Height of chamber is comparable with half height of cavity for fluid working medium. Generator is installed in vessel and used as heater. At that part of outer surfaces of generator is in contact with fluid working medium, and channels communicated with fluid working chamber and container outlet branch pipe are made on its outer surfaces at gas-generating charge location. Branch pipe for working gas outlet from the generator is located on the side of the actuation system. Portion of the pipeline connecting the generator to the vessel inlet branch pipe can be made in the form of a helical spring and is installed on the outer surface of the container outlet branch pipe. In the outlet pipe wall of the container there can be a free cavity coaxially to the outlet hole, which is pneumatically connected to the generator branch pipe for the working gas outlet and to the vessel inlet branch pipe.

EFFECT: technical result is reduction of weight, dimensions and operation time of device in conditions of negative temperature; simple device layout; increased reliability of operation.
