Abstract:
A valve drive device for actuating valves of an internal combustion engine a rocker arm device and a switchover device that includes at least two actuators for the at least one rocker arm device. The two actuators respectively include a switching element adjustable between a first position and a second position; a resetting device for resetting the switching element with a resetting force into the second position; a holding coil for offsetting the resetting force of the resetting device; a switching coil that counteracts the resetting force during operation. The switching coil and the holding coil adjust the switching element into the first position.
