    Patent number: 10443454
    Abstract: A valve drive device for an internal combustion engine is disclosed. The valve drive device has an axially displaceable cam element and an adjusting device with a first engagement element which displaces the cam element axially into a first switching position and a second engagement element which displaces the cam element axially into a second switching position. The adjusting device has a first slotted guide track in which the first engagement element is guided in the first switching position and a second slotted guide track in which the second engagement element is guided in the second switching position. The first engagement element is positively coupled to the second engagement element. The adjusting device includes a triggering device which holds the first engagement element fixedly in the second switching position counter to a restoring force. A method for axial displacement of a rotating cam element is also disclosed.
