Abstract

The invention relates to a device for camshaft adjustment in an internal combustion engine, having a lifting profile element which is provided in a rotationally fixed manner on an axially movable mounted camshaft and which provides a control groove, and having a control unit for generating a predetermined axial movement of the camshaft, wherein the control unit has a tappet unit which is preferably movable radially with respect to the camshaft and which is designed to controllably engage into the lifting profile element, wherein the lifting profile element forms a first control groove which is designed to interact with the tappet unit at a first penetration depth in order to describe a first axial movement of the camshaft, and the lifting profile element forms a second control groove which is designed to interact with the tappet unit at a second penetration depth, which differs from the first penetration depth, in order to describe a second axial movement, which differs from the first axial movement, of the camshaft.
