    • There is provided a high-pressure fuel pump drive circuit for manipulating the electric current to be passed to a solenoid coil for controlling a high-pressure pump. This circuit is characterized in that a first switching element, the solenoid coil and a second switching element are connected in series with each other in a rout from a source voltage side to the ground side, that a flywheel diode for passing electric current to a power source is disposed parallel with the solenoid and with the first switching element, and that a Zener diode connected with the power source is disposed parallel with the second switching element, wherein a counter electromotive force to be developed at the opposite ends of solenoid coil on the occasion when the second switching element is changed from ON to OFF is consumed by the flywheel diode provided that the first switching element is in a state of ON, and the counter electromotive force is more rapidly consumed by the Zener diode provided that the first switching element is turned OFF.
    • 提供了用于操纵要通过到用于控制高压泵的螺线管线圈的电流的高压燃料泵驱动电路。 该电路的特征在于,第一开关元件,螺线管线圈和第二开关元件在从源极电压侧到接地侧的路径中彼此串联连接,用于将电流传递到电力的续流二极管 源极与螺线管和第一开关元件平行设置,并且与电源连接的齐纳二极管与第二开关元件平行设置,其中在电磁线圈的相对端处形成的反电动势 只要第一开关元件处于ON状态,并且反电动势被齐纳二极管更快地消耗,则由续流二极管消耗第二开关元件由ON变为OFF的情况,只要第一开关元件 关闭。
