CRYOGENIC RESERVOIR Russian patent published in 1994 - IPC

FIELD: cryogenic engineering. SUBSTANCE: cryogenic reservoir has inner cryogenic vessel, casing, multilayer shield-vacuum heat insulation laid between walls of cryogenic vessel and casing, built-in cryosorption pump located inside heat insulated chamber on the outer wall of cryogenic vessel, tight envelope with thermovacuum valves located in heat-insulated chamber and embracing the porous shield in heat-insulated chamber and embracing the porous shield of the cryosorption pump. Thermovacuum valves are provided with thermosensitive elements made of ferromagnetic material at Curie point equal to desorption temperature of adsorbent. Reservoir is provided with safety valve. Chamber formed by tight envelope is brought in communication with system of preliminary evacuation through vacuum pipe line and vacuum valve. EFFECT: enhanced efficiency. 2 cl, 2 dwg
