- the inner pole 310 is partially encapsulated with the plastic material 98 together with the insert part 294 and the magnetic disk 304.
- a residual air gap disk 315 is molded onto the inner pole 310.
- the residual air gap disk 315 serves to represent an axial residual air gap between the inner pole 310 and an armature, not shown in FIG. 16.
- the residual air gap disk 315 may be formed of the plastic material 98, as shown. This provides the advantage that the pole tube 24 with the inserts 294 to 296, the magnet ring disks 304 to 306 and the inner pole 310 can be produced together with the residual air gap disk 315 in an injection molding process.
- FIG. 17 shows in simplified form an actuator device 401 with a single-acting electromagnet 404.
- an armature 408 is biased in its illustrated open position.
- the single-acting electromagnet 404 comprises a coil 41 1.
- the coil 41 1 When the coil 41 1 is energized, then the armature 408 is pulled against the biasing force of the spring 406 in Figure 17 down.
- the coil 41 1 is arranged in a bobbin 415.
- the bobbin 415 is integrated in a pole tube 424 in a manner similar to that shown in FIGS. 9 and 16.
- the pole tube 424 comprises combination bodies 421; 422, which are partially encapsulated with a plastic material 425.
- the combination bodies 421; 422 comprise, as in the embodiment shown in Figure 16, 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 By 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.
