CRYOGENIC FUEL TANK OF VEHICLE OPERATING ON LIQUEFIED NATURAL GAS Russian patent published in 2020 - IPC F02M21/02 B60K15/07 F17C13/00 

FIELD: cryogenics.

SUBSTANCE: invention relates to cryogenic equipment and can be used as fuel tank of transport facility operating on liquefied natural gas. Disclosed is a cryogenic fuel tank of a vehicle operating on liquefied natural gas, consisting of two vessels arranged one inside the other, the inner vessel outside is wound with thermal insulation, and the inter-wall space between the inner and outer vessels is evacuated. All cryogenic lining of cryogenic fuel tank is assembled into one housing – monoblock, which contains all shutoff valves, outlets to instruments etc., and solid unit communicates internal vessel with filling and emergency inputs / outputs. Due to application of this scheme, time of production in shop is reduced, since monoblock is assembled and adjusted in laboratory, reduced number of welds on outer casing, which statistically reduces amount of rejects of weld seam and facilitates maintenance, as well as repair and defect search during de-evacuation of inter-vessel space.

EFFECT: reduced number of welded joints and reliable fixation of inner vessel relative to outer one, as well as increased safety of vessel during operation.
