Abstract
An apparatus having an electromagnetic actuator for operating an actuating element, in particular an inlet or exhaust valve of an internal combustion engine, which includes an electromagnetic unit via which an armature which is mounted such that it may move and is operatively connected to the actuating element may be moved, and having a measurement apparatus which includes at least one inductive measurement element at least for detecting a position of the armature, and in particular having a spring mechanism which acts on the actuating element. At least one inductive measurement element may be firmly connected to the armature.
Claims11
An apparatus, comprising:
- an electromagnetic actuator configured to operate an actuating element, the electromagnetic actuator including an electromagnetic unit and an armature, the armature movably mounted via the electromagnetic unit and operatively connected to the actuating element, the armature being configured to be movable in accordance with the electromagnetic unit;
- a measurement apparatus having at least one inductive measurement element configured at least to detect a position of the armature, the at least one inductive measurement element fixedly connected to the armature;
- and
- a spring mechanism configured to act on the actuating element.
