Abstract[English]
An apparatus and method for storage of a liquid cryogen, particularly liquid hydrogen, is provided. The apparatus may include: a cryogenic pump (20) positioned to receive the liquid cryogen from a liquid cryogen storage tank (10), wherein the cryogenic pump (20) comprises: a piston ring leak conduit (24) in fluid communication with a piston ring leak outlet (23) on the cryogenic pump (20) and the headspace (5) of the liquid cryogen storage tank (10); a piston ring leak check valve (17) disposed on the piston ring leak conduit (24); a piston ring leak vent valve (40) in fluid communication with the piston ring leak conduit (24); a pump discharge conduit (22) in fluid communication with the pump discharge outlet (21); and a pump discharge vent valve (19) in fluid communication with the pump discharge conduit (22).[French]
L'invention concerne un appareil et un procédé de stockage d'un liquide cryogénique, en particulier de l'hydrogène liquide. L'appareil peut comprendre : une pompe cryogénique (20) positionnée pour recevoir le liquide cryogénique provenant d'un réservoir de stockage (10) de liquide cryogénique, la pompe cryogénique (20) présentant : un conduit de fuite (24) de segment de piston en communication fluidique avec une sortie de fuite (23) de segment de piston sur la pompe cryogénique (20) et l'espace libre (5) du réservoir de stockage de liquide cryogénique (10); un clapet de non-retour de fuite (17) de segment de piston disposé sur le conduit de fuite (24) de segment de piston; une soupape de purge de fuite (40) de segment de piston en communication fluidique avec le conduit de fuite (24) de segment de piston; un conduit de refoulement (22) de pompe en communication fluidique avec la sortie de refoulement (21) de pompe; et une soupape de purge (19) de refoulement de pompe en communication fluidique avec le conduit de refoulement (22) de pompe.
