CRYOGENIC FLUID RESERVOIR Russian patent published in 1996 - IPC

FIELD: cryogenic engineering. SUBSTANCE: fitted in vacuum chamber of overflow siphon of cryogenic fluid reservoir is heat supply line whose one end has thermal contact with outer tube of siphon above reservoir neck and other end has thermal contact with inner tube of siphon in its lower portion. Mounted after siphon is evaporator which is connected with it; outlet of evaporator is connected in parallel with gas zone of reservoir and with consumer. Reservoir has overflow siphon 1 which consists of inner tube 2 and outer tube 3 arranged concentrically, with vacuum chamber 4 between them; siphon is located in neck 5 of reservoir 6. Evaporator 7 is connected through valve 8 and branch pipe 9 with vapour zone of reservoir 6 and is connected in parrallel with consumer through valve 10. Heat supply line 11 is located in vacuum chamber 4 of siphon 1. EFFECT: enhanced reliability. 2 dwg
