Abstract
An electromagnetic lifting armature actuator, in particular for valves, comprises an armature rod which can be shifted in the direction of its longitudinal axis, and a magnetic yoke comprising a first yoke leg and a second yoke leg which is coaxial to the armature rod. A first magnet coil encloses the first yoke leg and a second magnet coil encloses both the second yoke leg and the armature rod. One of the magnet coils is a working and measuring coil which can be selectively used for enhancing the magnetic force or for determining a position of the movable armature rod.

An electromagnetic lifting armature actuator, in particular for valves, comprising an armature rod which can be shifted in a direction of a longitudinal axis;
- a magnetic yoke comprising a first yoke leg and a second yoke leg which is coaxial to the armature rod;
- a first magnet coil enclosing the first yoke leg and a second magnet coil enclosing both the second yoke leg and the armature rod;
- and
- wherein one of the first and second magnet coils is a working and measuring coil which can be selectively used for enhancing a magnetic force or for determining a position of the armature rod.
A valve, in particular a miniaturized magnet valve, comprising:
- a lifting armature actuator comprising;
- an armature rod which can be shifted in a direction of a longitudinal axis;
- a magnetic yoke comprising a first yoke leg and a second yoke leg which is coaxial to the armature rod;
- a first magnet coil enclosing the first yoke leg and a second magnet coil enclosing both the second yoke leg and the armature rod;
- wherein one of the first and second magnet coils is a working and measuring coil which can be selectively used for enhancing a magnetic force or for determining a position of the armature rod;
- and
- wherein the armature rod has an outer axial end face provided with a sealing body which cooperates with a sealing seat of the valve.
