PURPOSE:To suppress generation of vapor in fuel remaining in the vicinity of a fuel injection valve after an engine is stopped, in a fuel supplying device for an internal combustion engine suitably used in an inter-cylinder injection type internal combustion engine. CONSTITUTION:A fuel supply device for an internal combustion engine is provided with a fuel supply passage 3A and a fuel return passage 3B which are provided between a fuel injection valve 1 and a fuel tank 2 in an internal combustion engine, a fuel pump 5 provided between the fuel tank 2 and the fuel injection valve 1 in the fuel supplying passage 3A, and a fuel pressure control means 10 provided in the fuel returning passage 3B and for regulating pressure of fuel remaining in the vicinity of the fuel injection valve 1 to a prescribed pressure value. And also the device is provided with a check valve 20 provided in the fuel supplying passage 3A laid in the vicinity of the fuel pump 5 so as to block reverse flow of fuel remaining downstream from the fuel pump 5, and an accumulator 19 mounted in the vicinity of the fuel injection valve 1 located downstream from the fuel pump 5 so as to maintain fuel pressure to a prescribed level. |
