    • A fuel control device (11) which is provided on a fuel outlet side of a low-pressure pump (3) for controlling a fuel supply pressure from the low-pressure pump (3) to a predetermined pressure includes a pressure control valve (50) for controlling a fuel pressure of the fuel outlet side and a fuel takeout valve (60). The fuel takeout valve (60) has a valve opening pressure which is smaller than a valve opening pressure of the pressure control valve (50), a drain port (50C) of the pressure control valve (50) and a drain port (61C) of the fuel takeout vale (60) are connected to a fuel low-pressure side by way of a drain pipe (13), and back pressures of pistons (52), (62) are maintained at a fuel-low-pressure-side pressure of the low-pressure pump (3).
    • 燃料控制装置(11)设置在用于控制从低压泵(3)到预定压力的燃料供给压力的低压泵(3)的燃料出口侧,包括压力控制阀(50 ),用于控制燃料出口侧的燃料压力和燃料取出阀(60)。 燃料取出阀60具有小于压力控制阀50的开阀压力的开阀压力,压力控制阀50的排出口(50C)和排出口61 燃料出口阀(60)的C)通过排水管(13)连接到燃料低压侧,活塞(52),(62)的背压保持在燃料低压 低压泵(3)的侧压。

    • A fuel supply pump, which is simple in construction and easy to produce and is capable of efficiently pressurizing a high flow rate of fuel, is provided. The fuel supply pump (50) includes a housing (52), a plunger barrel (53), a plunger (54) for pressurizing fuel, which is installed in the plunger barrel (53) so as to be allowed to move up and down, a cam (60) installed in rotation way below the plunger (54), a tappet structure body (6) installed between the cam (60) and the plunger (54) to transmitting the turning force, serving as a lifting force, from the cam shaft (3) to the plunger (54), a tappet structure body (6) installed between the cam (60) and the plunger (54) and provided for transmitting a upward or downward movement of the cam (60) caused by the rotation of the camshaft (3) to the plunger (54); and a return spring (68) for setting lowering force to the plunger (54), which is installed between the tappet structure body (6) and the plunger barrel (53).
    • 一种燃料供给泵,其结构简单,易于生产,并且能够有效地加压高流量的燃料。 燃料供给泵(50)包括壳体(52),柱塞筒(53),用于加压燃料的柱塞(54),其安装在柱塞筒(53)中以允许上下移动 ,安装在所述柱塞(54)下方的旋转的凸轮(60),安装在所述凸轮(60)和所述柱塞(54)之间的挺杆结构体(6),以将作为提升力的转动力从 所述凸轮轴(3)连接到所述柱塞(54);挺杆结构体(6),安装在所述凸轮(60)和所述柱塞(54)之间并且被设置成传递所述凸轮(60)的向上或向下运动, 凸轮轴(3)向柱塞(54)的旋转; 以及安装在挺杆结构体(6)和柱塞筒(53)之间的用于设置对柱塞(54)的降低力的复位弹簧(68)。
