Patent ID: 7793642

Claim:
A fuel supply apparatus for supplying fuel from a fuel tank to a high-pressure fuel system that accumulates the fuel at a high pressure, supplies the fuel to an internal combustion engine at the high pressure, and returns excessive fuel, which is a part of the fuel that is once accumulated in the high-pressure fuel system yet not supplied to the internal combustion engine, to the fuel tank, the apparatus comprising: a fuel pump that draws the fuel from the fuel tank and discharges the fuel to the high-pressure fuel system; a filter unit that has a filter element located on a downstream side of the fuel pump to remove foreign matters contained in the fuel discharged from the fuel pump; a jet pump that has a nozzle installed in a fuel supply passage between the fuel pump and the filter element to inject the fuel to a downstream side of the nozzle in the fuel supply passage; and an introducing passage that introduces the excessive fuel from the high-pressure fuel system to the downstream side of the nozzle.
