Abstract

A variable valvetrain (2) for actuating a valve (70) of an internal combustion engine, comprises an actuation system for periodically opening and closing the valve (70); and a control system (90. 100). The control system comprises a gas position operating element (92. 102), whose position is variable in dependence on a gas command; a movable adjustment element (95, 105) which is so coupled to the support body (80) that by movement of the adjustment element the position of the first rotational axis (14) is changed and thereby the valve lift is adjusted; and a force-fit element (94, 104) connecting the gas position operating element (92. 102) in a force-fit manner to the adjustment element (95, 105).
