    • 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.
    • 目的:用于供应燃料的装置从喷射器供应燃料,同时通过确保密封,即使高压调节器的阀移动以控制高压调节器的压力,也可防止输送管的工作。 构成:用于供应燃料的装置包括安装在气缸盖(8)的下部单元中的输送管(5),安装在气缸盖的侧表面上的凸轮壳体(9),其具有高压泵(4 )和安装在凸轮壳体上的高压调节器(6)。 这里,高压调节器包括具有片单元的阀。 然后,阀门的单位硬度建立在800-1000Hv,以减少磨损。 因此,在不降低输送管的作用的同时从喷射器供给一定量的燃料的同时,正常地控制高压调节器的压力。
