Abstract: A valve train device, in particular for an internal combustion engine, includes a support element secured to a housing, at least one axially moveable cam unit associated with a valve, and at least one switch unit for axially moving at least one part of the cam unit having at least one displacement body which is provided to be introduced for axial movement at least functionally between the support element and the cam unit. The cam unit has at least three cam paths.

Abstract: An adjusting device, in particular for adjustment of a camshaft of an internal combustion engine, is disclosed. The adjusting device includes a brake unit which has at least one brake disc and at least one electromagnet for actuating the brake unit. The electromagnet has a yoke and an armature formed separately from the brake disc, where the brake disc is disposed at least partially spatially between the yoke and the armature of the electromagnet.
