Abstract: An electromagnetic positioning device has a long stretched out anchor plunger section as well as an anchor having an anchor body section axially continuing the latter, which in order to magnetically interact with a core unit and by energizing a stationary provided coil device is movably designed relative to the latter. The core unit is designed in such a way that it at least sectionally encompasses the anchor plunger section as well as the anchor body section with an expanded diameter relative to the anchor plunger section. The core unit is a multi-part design in the axial direction with a stationary core section, an axially movable core section and a variable core gap between the stationary and movable core section, and the movable core section and anchor are designed and joined together via a driver in such a way that, in response to energization, the movable core section moves, causing the core gap to close, and the driver drives the anchor in the axial direction.
