  • the pole tube 424 comprises combination bodies 421; 422, which are partially encapsulated with a plastic material 425.
  • the combination bodies 421; 422 include like the one in FIG. 16 illustrated non-claimed embodiment, each an insert, which is integrally connected to a magnetic disk.
  • the plastic material 425 serving for encapsulation of the combination bodies 421, 422 serves at the same time in a particularly advantageous manner for the representation of the bobbin 415.
  • the bobbin 415 is closed on the outside by a magnet pot or inference body 430.
  • the actuator device 401 is associated with a cooling and / or heating circuit, in particular a water circuit, a motor vehicle.
  • the water cycle includes a housing 450 having an inlet 451 and an outlet 452.
  • By an arrow 453 incoming cooling water is indicated.
  • By an arrow 454 leaking cooling water is indicated.
  • a closing body 455 a connection between the input 451 and the output 452 can be interrupted.
  • the closing body 455 is attached to an armature 408 facing away from the end of the plunger 410.
