FLUID MEDIUM TRANSPORTATION DEVICE Russian patent published in 2007 - IPC F04B47/00 F04B43/10 

FIELD: oil producing and other industries.

SUBSTANCE: invention relates to devices for lifting liquids from depths by means of hydraulic means. Proposed fluid medium transportation device contains two housing with elastic separators forming, in each housing at one side of separator, chamber for fluid medium to be transported, and at other side, chamber for working component. It has also pipelines with check valves to let in and let out transported medium and unit to let in and let out working component to change volumetric capacity of chambers. Housings are arranged one after the other. Pipeline to let out transported medium from chamber is provided with channel passing through second housing. Pipeline to supply transported medium into second chamber is provided with channel passing through first housing. Unit to let in and let out of working provided with pistons dividing cylinder into four space, two of which are connected with pipelines to let in and let out working component to elastic chambers and two others are connected with source of working component and with drain.

EFFECT: provision of transportation of fluid medium from well owing to reduction of cross dimensions of devices.
