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; anda 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); andwherein 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. 2. The device in accordance with claim 1, wherein the yoke unit further comprises flux-conducting connecting sections in the first and second magnetic-flux conducting circuits, wherein magnetic flux resistance of the flux-conducting connecting sections can be varied by formation of a predetermined maximum effective flux cross-section. 3. The device in accordance with claim 2, wherein the flux-conducting connecting sections are designed such that their magnetic flux resistance can rise above a threshold value determined by the flux cross section. 4. The device in accordance with claim 2, wherein the flux-conducting connecting sections are, implemented from a magnetically conducting material and form a number of yoke arms corresponding to a number of armature units, and wherein the yoke arms are positioned on the first yoke section. 5. The device in accordance with claim 4, wherein a respective yoke arm, with an associated armature unit, forms an air gap influenced by a setting position of the armature unit. 6. The device in accordance with claim 1, wherein the air gaps define a stop position of the armature units on respective second yoke sections and have dimensions that differ from one another. 7. The device in accordance with claim 6, wherein the air gaps have an air gap spacing of variable effectiveness. 8. The device in accordance with claim 1, further comprising spring agents, wherein at least one of the armature units is mounted or controlled against a restoring force of the spring agents. 9. The device in accordance with claim 8, wherein the restoring force acting on the armature units is set up differently for at least two of the armature units. 10. The device in accordance with claim 1, wherein at least one of the first yoke section, the second yoke sections, and a flux-conducting section between the first yoke section and the second yoke sections, is implemented as at least one of a stackable sheet element and a layered arrangement of a plurality of sheet elements.
