PRESS-FEED DEVICE INSTALLED FOR PRESS-FEEDING FUEL FROM FUEL TANK TO INTERNAL COMBUSTION ENGINE, OF AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To provide such device that a pressure can be observed in particular accurately in a supply pipe road by improving a press-feed device, installed for press-feeding a fuel from a fuel tank to the internal combustion engine of an automobile, with a form in which a press-feed pump and a means for controlling the internal pressure f the supply pipe road conducted from the press-feed pump to the internal combustion engine are installed. SOLUTION: A supply pipe road 6 has a pressure control valve 7 which can control the operation by the pressure in a return pipe road 10 and the pressure control valve 7 is formed for shutting/releasing a branch pipe 8 conducted from the supply pipe road 6 to the fuel tank 1.
