Abstract (en)
[origin: WO2020014722A1] The invention relates to a variable valve drive device (1) for actuating at least one gas exchange valve, having a camshaft (2) rotatably mounted about an axis of rotation (2a) and having at least one cam element (3) adjustable via an adjusting device (20), wherein the cam element (23) is pivotably mounted about a pivot axis (3a) between at least a folded-in, first position (K) and a folded-out, second position (B) and wherein the adjustable cam element (3) is arranged adjacent to at least one basic cam (4a, 4b) in the direction of the axis of rotation (2a), wherein the adjusting device (20) has at least one push rod (6) arranged within the camshaft (2), wherein the push rod (6) has at least one ramp face (8) formed at least partly at an angle to the axis of rotation (2a) of the camshaft (2). The cam element (3) has a mating ramp face (13) interacting with the ramp face (8) of the push rod (6), which is formed at least partly at an angle to the axis of rotation (2a) of the camshaft (2).
