摘要： An electromagnetic actuator for operating a driven component includes first and second electromagnets having respective first and second pole faces oriented toward one another and defining a space therebetween; an armature disposed between the electromagnets and movable back and forth between the first and second pole faces in a direction of motion; a driving component attached to the armature for moving therewith as a unitary structure; and a resetting spring unit attached solely to the driving component or the driven component and exerting forces opposing movements of the armature caused by electromagnetic forces generated by the electromagnets. The resetting spring unit is in a relaxed state when the armature is in a mid position between the first and second pole faces and is in an armed state upon movement of the armature from the mid position in either direction. A mechanism connects the driving component with the driven component for effecting a transmission of moving forces from the driving component to the driven component to cause displacements of the driven component as a function of displacements of the armature and the driving component.
