Abstract
An electromagnetic actuator device having a core unit (12;50) having a coil means (16), which core unit is constructed for interacting with armature means (34,36,38,32,30) that are movably guided relatively to the core unit, as a reaction to an energizing of the coil means, wherein the armature means have a plurality of tappet units (30, 32), which are spatially spaced from one another and can be driven simultaneously, to which tappet units, permanent magnet means (34) are assigned in the direction towards the core unit, which permanent magnet means have a permanent magnetization along a respective movement longitudinal axis of the tappet units, wherein the plurality of tappet units that can be driven parallel to one another magnetically interacts with an identically poled end face of the core unit and the permanent magnet means have an axially identically directed permanent magnetization.
