Abstract : The invention relates generally to underwater breathing apparatus of the type known as 'cryogenic,' in that the breathing gas is derived, in whole or part, from liquefied gas. More particularly, the invention is directed to an underwater, cryogenic heat sink, in combination with such breathing apparatus, for maintaining a substantially constant low temperature circuit in the liquefied reservoir, whereby a number of operational advantages can be achieved.
