Abstract:
1. A valve drive arrangement for an internal combustion engine, including a camshaft ( 21 a ) with a cam element 16 a , 16 b ) axially movably supported on the camshaft ( 21 a ) in a rotationally fixed manner, the cam element ( 16 a , 16 b ) including a gate structure ( 17 a , 17 b ) with two intersecting guide paths ( 18 a , 19 a ; 18 b , 19 b ) and an actuation device ( 10 a ; 10 b ) including an actuator ( 14 a , 14 b ) with an engagement structure ( 13 a , 13 b ) and a shift element ( 11 a ; 11 b ) for engagement with the gate structure ( 17 a , 17 b ) for axially moving the cam element ( 16 a ; 16 b ), the shift element ( 11 a ; 11 b ) having a rotationally asymmetrical basic shape with a main axis extending in the direction of the guide paths having a length greater than the width of the guide paths for safely guiding the shift element ( 11 a , 11 b ) along the guide paths and through the intersection of the guide paths.
