DEVICE AND METHOD FOR SUPPLYING FLUID

摘要

Device for supplying fluid comprising a source tank for storing gaseous fuel at a cryogenic temperature in the form of a liquid-gas mixture, a cryogenic pump, the pump comprising a suction inlet connected to the lower part of the tank via a suction line, a high-pressure first outlet intended to supply high-pressure fluid to a user and a degassing second outlet connected to the upper part of the tank via a return pipe, the device being characterized in that it comprises a cryogenic buffer storage volume, a first pipe connecting the lower part of the buffer storage volume to the tank and a second pipe connecting the upper part of the tank to the buffer storage volume, and in that the device comprises a liquefaction member for liquefying the gas in the buffer storage volume.
