It is thus a polarized actuator. It is thereby achieved a superposition of the electromagnetic excitation flux generated by the exciter coil and the permanent magnetic flux to a total flux. It can thus be realized with a controlled current pulses bistable electromagnetic actuator. The actuator can be switched from one position to the other position by current pulses with the corresponding sign.
  • the electromagnetic actuator provides either the closing force or the opening force, or - in a bistable version - the closing force and the opening force for the sealing device.

  • the seals may be designed to perform a translatory, a rotary or a combined translational and rotational movement.
  • the seal carrier can be designed, for example, as a folding element, as a tilting element or as a slide, for example with a parallel guidance system.
  • the sealing profile can be optimized according to the application. For example, materials that are limited or not applicable to abrasive seals can be used. Well suited are, for example, soft rubber compounds. It is also possible to add magnetic particles to the material of the sealing profile. If one then applies a metal strip or the like to the opposite sealing surface, a magnetic attraction force results between the sealing profile and the sealing surface. As a result, the tightness can be further improved.
  • the interior of the elevator car can be completely sealed.
  • the partial movement A1 of a dog unit used to drive the opening movement of the seal (s) may be, for example, the same movement used to unlock the car door and / or the shaft door.
  • As part movement A1 can also apply an adjusting movement, which is carried out to bring a skid unit of the car door with shaft door rollers of a shaft door in combination.
  • the device is mechanically connected to the door leaf and moves when opening and closing the door solidarity with this.
  • Returning elements are preferably provided on the movable door seals in order to return the seals to the sealing position by themselves as soon as no force is exerted on the seals via the actuators.
  • the invention is particularly suitable for high-speed elevators and elevators which are to be specially sealed.
