<p>The invention provides an apparatus and a method for supplying liquefied gas, wherein the utilization rate of liquefied gas in a liquefied gas container is raised through a simple structure. Decompression paths (15a, 15b) and branch paths (17a, 17b) are respectively arranged in a plurality of gas supply systems; the decompression paths (15a, 15b) are provided with decompression valves (13a, 13b) and automatic open-close valves (14a, 14b); the branch paths (17a, 17b) are branches of decompression valves and automatic open-close valves formed through the branch valves (16a, 16b). In a gas supply system A, the branch valve (16a) of the branch path (17a) is closed, the automatic open-close valves (14a) is open, gas with the preset secondary side pressure formed through the decompression valve (13a) is supplied, when the liquefied gas amount of a liquefied gas container (11a) is a set value, the branch valve (16a) is open, the automatic open-close valves (14b) of a liquefied gas supply system B is open, and gas is supplied from the gas supply systems A and B.</p> |
