An electromagnetic actuating apparatus having an elongated actuating element () which forms an engagement area () at the end, can be moved by the force of a coil device (), (which is provided in a stationary manner) and has a permanent magnet (), in places, which are designed to interact with a stationary core area (), with a stationary bearing element () which acts as a yoke, being provided axially opposite the core area () for the actuating element (), which is in the form of a piston at least in places, and with the coil device () having at least one coil winding () which is arranged on a mount () and whose winding wires () are passed to contact elements () and are electrically conductively connected to them, with the connections () between the winding wires () and the contact elements () being arranged with vibration or oscillation damping with respect to the mount ().

Electromagnetic actuating apparatus

An electromagnetic actuating apparatus with an elongate actuating element (), which forms an engagement region () at the end and is capable of moving owing to the force of a coil device provided in stationary fashion, and sections of the actuating element have permanent magnets (), which are designed to interact with a stationary core region (), wherein a stationary bearing element () acting as a yoke is provided axially opposite the core region () for the actuating element (), at least sections of which are in the form of a piston, wherein the actuating element () has two sections (), wherein a first section (), which is arranged in the region of the permanent magnets (), is optimized in terms of the magnetic conductivity and a second section (), which is arranged in the engagement region, is optimized in terms of wear.
