Abstract

The invention concerns an electrically rotatable adjusting shaft (1) of a fully variable mechanical valve train of an internal combustion engine, said adjusting shaft comprising an adjusting cam. A rapid and exact rotation of the adjusting shaft (1) and the load regulation of the internal combustion engine depending thereon is achieved by the fact that an actuator (3) for rotating the adjusting shaft (1) comprises an adjusting lever (4) that is connected rotationally fast to the adjusting shaft (1), and the free end of the adjusting lever (4) can be loaded by a cam plate (6) that is driven by an electromotor (7).
