ABSTRACT:
In a high-pressure fuel pump, a bellows chamber communicates with a fuel tank. A volume chamber having a predetermined volume is arranged in a return passage which returns a fuel stayed in the bellows chamber to the fuel tank. The fuel which has stayed in a region in the return passage can be flowed into the volume chamber to be prevented from flowing back to the bellows chamber.
