    • An electromagnetically driven valve includes: a valve reciprocating to and fro along a direction in which the valve shaft extends; a disk connected to the valve; a first electromagnet including a first coil; a torsion bar, which is a first elastic member; and an ECU which controls the electromagnet force of the first electromagnet. This ECU controls electrical current so as, when weakening the electromagnetic force of the first electromagnet and separating the disk from the first electromagnet, to reduce the electrical current which flows in the first coil towards zero, after having temporarily increased it from a first holding current to a second holding current which is larger than the first holding current, and then, after the disk has separated from the first electromagnet, so as to flow a braking current for adjusting the speed of the disk.
    • 电磁驱动阀包括:沿阀轴延伸的方向往复往复运动的阀; 连接到阀的盘; 包括第一线圈的第一电磁体; 扭杆,其是第一弹性构件; 以及控制第一电磁铁的电磁力的ECU。 该ECU控制电流,从而当使第一电磁体的电磁力减弱并且将盘与第一电磁体分离时,在从第一保持电流暂时增加之后,将在第一线圈中流动的电流减小到零 到大于第一保持电流的第二保持电流,然后在盘与第一电磁体分离之后,以便流过用于调节盘的速度的制动电流。

    • A control apparatus of electromagnetic valve includes a valve body functioning as an intake valve or an exhaust valve of an internal combustion engine and an electromagnet for affecting an electromagnetic force relative to an armature provided on the valve body for actuating the valve body. A controler determines a target value regarding a force affecting the valve body when displacing the valve body from one displacement end to the other displacement end or a state quantity of the valve body varied in accordance with the force and controls the electromagnetic force of the electromagnet for attracting the armature to the one displacement side based on a deviation between the force or the state quantity and the target value so that the force or the state quantity conforms to the determined target value when displacing the valve body from the one displacement end to the other displacement end.
    • 电磁阀的控制装置包括用作内燃机的进气阀或排气阀的阀体和用于影响相对于设置在阀体上的用于致动阀体的电枢的电磁力的电磁体。 当将阀体从一个位移端移动到另一个位移端时,控制器确定关于影响阀体的力的目标值,或阀体的状态量根据力而变化,并且控制电磁铁的电磁力, 基于力或状态量与目标值之间的偏差将电枢吸引到一个位移侧,使得当将阀体从一个位移端移位到另一个位移端时,力或状态量与确定的目标值一致 位移端
