けたことを特徴とする燃料供給装置。 A pump supplies fuel from the fuel tank to an injector that injects fuel into the combustion chamber of the engine, and also supplies fuel to the fuel supply system via a return line when the fuel pressure rises above a certain level. In a fuel supply system equipped with a pressure regulator valve that returns the fuel to the fuel tank and maintains a constant fuel supply pressure, the fuel supply system operates at a higher pressure than the pressure regulator valve to supply fuel. A fuel supply device, characterized in that at least one second pressure regulator valve is inserted to return the return line to the fuel tank, and an opening/closing means for closing the return line depending on the operating state of the engine is provided. .
