Abstract:
A valve control for an internal combustion engine may include a tilt lever, a cam shaft, two cam groups arranged on the cam shaft, a roller bolt arranged on the tilt lever, and an adjusting assembly including a switching pin that engages through the roller bolt. The roller bolt may include two rotatable rollers. The switching pin may be adjustable into a switching position and into a home position. The switching pin may cooperate with a slotted guide of the cam shaft when in the switching position and may have no contact with the slotted guide when in the home position. When the switching pin is in the switching position, the two rollers may be axially adjustable via the adjusting assembly. The switching pin may be axially movable in the roller bolt and the two rollers may be axially movable on the roller bolt into one of two roller positions.
