DEVICE TO CREATE EXCESS PRESSURE AND CORRESPONDING METHOD Russian patent published in 2017 - IPC F17C5/00 F02K9/50 

FIELD: engines.

SUBSTANCE: invention relates to liquid-fuel rocket engines, particularly, to device to create excess pressure in first reservoir (2), containing at least second reservoir (3) made with possibility to contain cryogenic fluid medium, first loop (13) to create excess pressure to provide interaction between second reservoir (3) and first reservoir (2), wherein first loop (13) to create excess pressure comprises at least first heat exchanger (15) for cryogenic fluid medium flow heating, removed from second reservoir (3) through first loop (13) to create excess pressure, and second loop (14) to create excess pressure with compressor (31b) branching from first loop (13) to create excess pressure and communicating with second reservoir (3). Invention also relates to system (1) of at least first liquid fuel component supply into jet engine, containing at least first reservoir (2), made with possibility to contain first liquid fuel component, and device to create excess pressure in first reservoir (2).

EFFECT: invention provides creation of excess pressure in first reservoir comprising second reservoir with cryogenic fluid medium.
