Actuation device, valve means and operating method

摘要

The device (5) has an anchor (13) mounted in a stator and pivotably displacing between end positions in a pivot axis (7). Electromagnets (10) are arranged in the stator and produce electromagnetic attraction forces. Contact surfaces (20, 21) of the anchor lie at respective stator-sided contact surfaces (18) in the respective end positions of the anchor. A sensor (12) measures a parameter of magnetic field, which is produced by the electromagnets, during operation of the actuating device. The parameter is dependent on anchor movement and/or anchor position. Independent claims are also included for the following: (1) a valve device for influencing a gas flow in a gas path (2) a method for operating an actuating device.
