Abstract:
A fuel supply apparatus comprising:a fuel tank; a low-pressure fuel pump provided in the fuel tank; a low-pressure fuel intake pipe having one end thereof connected to the low-pressure fuel pump; a first branch pipe having one end thereof connected to the other end of the low-pressure fuel intake pipe; a first high-pressure fuel supply assembly which is connected to the other end of the first branch pipe, pressurizes a low-pressure fuel from the low-pressure fuel intake pipe into a high-pressure fuel, and discharges the high-pressure fuel; a second branch pipe having one end thereof connected to the other end of the low-pressure fuel intake pipe; and a second high-pressure fuel supply assembly which is connected to the other end of the second branch pipe, pressurizes a low-pressure fuel from the low-pressure fuel intake pipe into a high-pressure fuel, and discharges the high-pressure fuel; wherein the first branch pipe and the second branch pipe are composed of rigid pipes so as to restrain fuel pressure surges in said low-pressure fuel intake pipe.
