Abstract

A device for adjusting a camshaft of an internal combustion engine includes a lifting profile assembly rotationally fixed on an axially movable camshaft, and has a control groove having a depth that varies along a rotation direction, an actuator to cause axial movement by controlled engaging in the control groove, and an electromagnetically drivable tappet unit that cooperates with the control groove such that, when rotating, a reset or driver effect is exerted on the tappet unit, wherein the tappet unit has at least two independently drivable tappets, the control groove engages a first individual tappet, forms a radially peripheral wall along a peripheral groove side whereby a second individual tappet is positioned outside the control groove during rotation, and a ramp section cooperating with the second individual tappet whereby the second individual tappet is reset or driven when the first individual tappet is reset or driven.
