Abstract (en)
[origin: EP1503048A1] The valve drive (2) has a sliding cam device (10) with cam paths lying next to each other with different cam forms (NI,NII,NIII) and hoisting curves that function together with actuators (22-25). The actuators have control pins (18-21) for adjusting the sliding cam device. One of the hoisting curves has different hoisting curve sections for an engaged control pin of a corresponding actuator. An independent claim is also included for the internal combustion engine including the valve drive.
