Zusammenfassung:	A variable camshaft includes a base shaft, an axially movable structure, and an actuator. The axially movable structure includes a plurality of lobe packs and at least one barrel cam defining a control groove having an engagement region, a first shift region, a balancing region, a second shift region and a disengagement region. The actuator includes at least one pin operatively configured to move relative to the actuator body between a retracted position and an extended position into the control groove. The axially movable structure moves axially relative to the base shaft the pin is in the extended position and is at least partially disposed in one of the first or second shift regions of the control groove.
