PURPOSE:To enable to efficiently consume the liquefied gas stored in each liquefied gas tank, by providing a nonreturn valve to a flow passage connecting a liquefied gas tank and a collecting pipe passage. CONSTITUTION:A nonreturn valve 10, which allows a gas-flow to flow toward a regulator but forbids the gas-flow to flow in the reverse direction, is provided to a flow passage that connects each liquefied gas tank and a collecting pipe passage. When liquefied gas remains in the liquefied gas tank, this nonreturn valve 10 opens the flow passage of the nonreturn valve 100, because the gas pressure is stronger than the pushing force of a spring. On the other hand, when liquefied gas remaining in the liquefied gas tank becomes almost null, the nonreturn valve 10 automatically closes the flow passage, because the gas pressure in the flow passage becomes weaker than the pushing force of the spring. With this constitution, the fuel consumption efficiency of the liquefied gas tank can be enhanced. |
