Patent ID: 7822534

Claim:
A fuel supply device for an internal combustion engine in which fuel drawn up from a fuel tank by a fuel feed pump is pressurized and stored in a pressure accumulator and the fuel stored in the pressure accumulator is injected from a fuel injection valve, comprising: a return passageway connecting the pressure accumulator and the fuel tank; a control valve that is provided on the return passageway and that is switched between a communicating position for connecting the pressure accumulator and the fuel tank in communication and a shutting-off position for shutting off the pressure accumulator and the fuel tank from each other in communication; and an operation control portion that switches the control valve to the communicating position and operates the fuel feed pump if a predetermined stop condition for stopping the internal combustion engine is satisfied, wherein if the predetermined stop condition is satisfied, the operation control portion initially switches the control valve to the communicating position and operates the fuel feed pump, and then switches the control valve to the shutting-off position and operates the fuel feed pump.
