Abstract (en)
[origin: JPH06307599A] PURPOSE: To provide a self-contained device superior in strength and reliability and adapted to foods refrigeration equipment in particular by connecting two meandering tubes to a cryogenic liquid reservoir, connecting them to a pump respectively and arranging check valves, carburetors, and control valves therein. CONSTITUTION: A cryogenic liquid reservoir 1 is formed of double walls 11 , 22 and connected to two meandering tubes 21 , 22 for taking out the cryogenic liquid stored therein. The both meandering tubes 21 , 22 have both check valves 41 , 42 , both carburetors 51 , 52 and both control valves 61 , 62 arranged therein. A pump 7 is connected to the both meandering tubes 21 , 22 to pump the taken- out cryogenic liquid to using facilities, for example, foods refrigeration equipment. The both control valves 61 , 62 are controlled by a converter 9 and an electronic controller 12 based on the both pressure of the respective meandering tubes 21 , 22 . On the other hand, both portable grips 181 , 182 are attached to the upper part of the cryogenic liquid reservoir 1.
