Device for adjusting a camshaft of an internal combustion engine

A device for adjusting an axially movably mounted camshaft of an internal combustion engine, comprising a lifting profile assembly (10) which is provided in a rotationally fixed manner on or at the camshaft, wherein the lifting profile assembly (10) forms a control groove (12), having a groove depth that varies along a direction of rotation, and comprising actuating means (FIG. 4) which are designed to cause an axial movement by controlled engaging in the control groove, and which have an electromagnetically drivable tappet unit (P1, P2),

• wherein the tappet unit cooperates with the control groove such that, when rotating, the control groove can exert a reset or driver effect on the tappet unit in a predetermined groove section,
• wherein
• the tappet unit has at least two neighboring individual tappets (P1, P2),
• said tappets being independently drivable,
• the control groove, designed to engage using a first of the individual tappets (P2), forms a radially peripheral wall at least along a peripheral groove side such that a neighboring second of the individual tappets (P1) is positioned outside the control groove during rotation,
• and the lifting profile assembly is provided with a radially height-variable ramp section (20) positioned axially laterally outside the control groove for cooperating with the second individual tappet, such that a resetting and/or driving of the second individual tappet (P1) is caused when the first individual tappet (P2) is reset or driven against a tappet drive direction using the control groove, wherein the radially height-variable ramp section (20) has a radial vertical profile which runs parallel to a course of the groove depth.
