Abstract:
The invention concerns an electromagnetic actuator (7) with a coil (8) and at least two armatures (12, 17) being movable along an axis (16) and being acted upon by a magnetic field generated by the coil (8). It is endeavoured to achieve large control opportunities by simple means. For this purpose, it is provided that one armature (12) is acted upon by a larger drive force from the magnetic field than another armature (17).
