DEVICE FOR SUPPLYING FUEL

摘要

PURPOSE: A device for supplying fuel supplies fuel from an injector while preventing working of a delivery pipe from being lowered by securing the sealing even if the valve of a high-pressure regulator moves for controlling the pressure of the high-pressure regulator. CONSTITUTION: A device for supplying fuel contains a delivery pipe(5) installed in the lower unit of a cylinder head(8), a cam case(9) installed on the side surface of the cylinder head with a high-pressure pump(4) and a high-pressure regulator(6) installed on the cam case. Herein, the high-pressure regulator contains a valve having a sheet unit. Then, the hardness of the sheet unit of the valve is established for 800-1000Hv to reduce abrasion. Therefore, the pressure of the high-pressure regulator is controlled normally while supplying a certain amount of fuel from an injector without lowering the working of the delivery pipe.
