SYSTEM TO STORE CRYOGENIC LIQUID FOR SPACECRAFT Russian patent published in 2014 - IPC B64G1/40 F17C13/00 

FIELD: heating.

SUBSTANCE: invention relates to system of cryogenic liquid storage, in particular, for a propulsion system of a spacecraft. The system comprises at least one reservoir (1A) for liquid and an outer shell (1B), separated from the reservoir (1A) by vacuum space. In this space there is a multi-layer superinsulator (20). There is a device (14) for control of fuel supply, made of material with high heat conductivity and cooled by a cryorefrigerator (11). This device serves to confine liquid inside the reservoir (1A) under conditions of microgravity. A pouring pipeline (21) is located in the lower (when on the Earth) part of the reservoir (1A) and is surrounded with a double wall of vacuum insulation. A discharge pipeline (22A), which connects the reservoir (1A) with an outer shell (1B), has the length of the inner part that is not less than the half of the reservoir (1A) diameter.

EFFECT: increased structural perfection of reservoirs with hydraulic valves and safety of service personnel.
