<P>PROBLEM TO BE SOLVED: To provide a fuel gas supplying device which has high pressure tanks positioned in parallel and each equipped with a shut-off valve and a regulator and which can make good use of remaining gas left between the shut-off valve and the regulator and control efficiently a fuel gas amount to be consumed or exhausted during a system stoppage, and can prevent an increase of a fuel cost and quickly stop the system. <P>SOLUTION: This device is composed of high pressure fuel tanks connected in parallel facing a fuel gas receiving unit, a shut-off valve equipped each on a high pressure fuel tank, a regulator which is fixed each on a high pressure fuel tank in a part of a passage which connects each shut-off valve and the fuel gas receiving unit and which is positioned in parallel against the fuel gas receiving unit, and a controlling means which controls an opening/closing of each shut-off valve. The above controlling means will close at least one of the valves, selected in accordance with a size of regulator pressure out of the shut-off valves which has a fuel gas more than a predetermined volume in-between a regulator. <P>COPYRIGHT: (C)2007,JPO&INPIT |
