Abstract
A bistable electromagnetic actuating apparatus () having an actuating element (), which forms an engagement region () at the end and can be moved axially between two end positions, in particular for engaging in a control groove in a cam of an internal combustion engine, and having a coil device () which is provided in a stationary manner relative to the actuating element () and is designed to exert a force on said actuating element, wherein the actuating element () has permanent magnets () which are designed to interact with a core region () which is provided in a stationary manner relative to the actuating element (), and wherein the coil device () is designed to generate a counterforce, which counteracts a retaining force of the permanent magnets () and releases said permanent magnets from the core region (), in response to an electronic actuation signal, and wherein a spring is arranged such that it applies a spring force to the actuating element () in an axial direction which faces away from the core region ().
