An electromagnetic actuator device, comprising a coil unit (14), which surrounds a first yoke section (13) of a stationary yoke unit and can be activated by energizing the coil unit; and armature elements (10, 12), which are guided so as to be movable relative to the yoke unit and which interact with an output-side actuating partner and which can be driven in order to perform an actuating movement. The armature elements interact with at least one second yoke section (15, 16) of the yoke unit to form an air gap (26, 28) for a magnetic flux produced by the activated coil unit. |

1. An electromagnetic actuator device, comprising:
a stationary yoke unit comprising a first yoke section (13) and at least two second yoke sections (15, 16); at least two armature units (10, 12) moveable relative to the at least two second yoke sections (15, 16) so as to define first and second air gaps (26, 28) between respective armature units and second yoke sections, said armature units (10, 12) also being separately moveable relative to each other; and a coil unit (14) surrounding the first yoke section (13), wherein the armature units (10, 12) and the second yoke sections (15, 16) are radially outside of the coil unit (14), wherein activation of the coil unit (14) controls movement of the armature units (10, 12) relative to the second yoke sections (15, 16); wherein the first yoke section (13), second yoke sections (15, 16) and armature units (10, 12) define at least first and second magnetic flux-conducting circuits, wherein each of the first and second magnetic flux-conducting circuits runs through the first yoke section (13), respective second yoke sections (15, 16), respective armature units (10, 12) and respective air gaps (26, 28); and wherein alteration of an air gap of one of the first and second magnetic flux-conducting circuits causes a flux alteration in the other of the first and second magnetic flux-conducting circuits. |
