REFRIGERATION LIQUID STORAGE CONTAINER

摘要

An arrangement for storing cryogenic liquid comprises a Dewar-flask-like vessel. The vessel is filled completely with a material able to absorb a cryogenic substance when said substance is in liquid form but only capable of absorbing said substance to a limited extent when said substance is in gas form. Adjacent to the mouth of said vessel and externally thereof there is provided a cavity, which is arranged to cooperate with means by which any gases formed in said cavity can be released to atmosphere when the pressure in said cavity exceeds a given pressure.
