PROBLEM TO BE SOLVED: To provide a fuel supply device feeding liquefied gas fuel stored in a fuel tank in a simple structure not requiring external power such as a feed pump. SOLUTION: The fuel supply device 100 for feeding DME fuel from the fuel tank 10 storing the DME fuel as the liquefied gas fuel, includes an air compressor 30 supplying compressed air, a check valve 40 adjusting the supply amount of the compressed air from the air compressor 30, and a movable partitioning wall 12 as a pressure responsive member for pressurizing a storage chamber 11 displaced corresponding to the pressure in the back pressure chamber 13. The fuel tank 10 includes the storage chamber 11 storing the DME fuel, and the back pressure chamber 13 for storing the compressed air supplied from the air compressor 30. The DME fuel in the storage chamber 11 is fed by the check valve 40 raising the pressure of the back pressure chamber 13. COPYRIGHT: (C)2010,JPO&INPIT
