Embodiment Construction

[0043] The means for supplying the fluid comprises a source tank 2 for storing gaseous fuel at low temperature in the form of a liquid-gas mixture. Tank 2 is preferably of the double-walled type with an insulating vacuum between the two walls.

[0044] The device comprises a cryopump 3 equipped with a suction inlet 4 connected to the lower part of the tank 2 via a suction line 5 .

[0045] The pump 3 comprises a high pressure first outlet 6 and a degassed second outlet 7 for supplying pressurized fluid (liquid) to the user. The degassing outlet 7 is connected to the upper part of the tank 2 via a return line 9 . For example, the end of the return duct 9 comprises a multi-jet dispensing nozzle 17 in the upper part of the tank 2 .

[0046] The device 1 also comprises a different cryogenic buffer storage body 8 and a first conduit 10 connecting the lower part of the buffer storage body 8 to the tank 2 , preferably to the lower part of the tank 2 . The device 1 comprises a second...

Abstract

The present invention relates to a device and a method for supplying fluid. The 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.

Description

technical field [0001] The present invention relates to a device and method for supplying fluid. [0002] More specifically, the present invention relates to a device for supplying a fluid comprising a source tank for storing gaseous fuel at low temperatures in the form of a gas-liquid mixture and a cryogenic pump comprising A suction inlet connected to the lower part of the tank, a high pressure first outlet for supplying high pressure fluid to the user and a degassing second outlet connected to the upper part of the tank via a return line. [0003] The invention relates to a device for supplying a fluid (liquid or gas) under pressure from a tank of liquid stored at cryogenic temperatures. To obtain pressurized gas, the pumped liquid can be evaporated in an evaporator. Background technique [0004] High-pressure cryogenic liquid pumping stations, including pumps used to draw cryogenic liquid from an insulated tank under vacuum and compress it, face the problem of how to m...
