    • An electromagnetic actuating device comprises a solenoid coil to which a control current can be applied and an armature associated with the solenoid coil which is adapted to carry out movements which are dependent upon a control current flowing through the solenoid coil and a spring arrangement for biassing the armature into opposite directions, with a holding position being defined which is assumed by the armature at a holding current through the solenoid coil, with the holding current flowing through the solenoid coil being variable to a higher value or to a lower value with the armature not leaving the holding position, and both the higher and the lower current value being able to be dimensioned in such a manner that interference influences on the magnetic and spring forces which actuate the armature do not bring the armature from its holding position into an actuated position which is different from the holding position.
    • 电磁致动装置包括可施加控制电流的螺线管线圈和与螺线管线圈相关联的电枢,该电枢适于执行取决于流过电磁线圈的控制电流的运动和用于偏置电磁线圈的弹簧装置 衔铁处于相反的方向,其中保持位置被电枢以保持电流通过螺线管线圈所假设,保持电流流过螺线管线圈可变为更高的值或较低的值,而电枢不是 离开保持位置,并且较高和较低的电流值都能够以使得驱动电枢的磁力和弹簧力受到干扰的影响不会使电枢从其保持位置进入致动位置的方式来确定尺寸, 与保持位置不同。
