摘要

The variable valve gear for internal combustion engines includes an intermediate lever (4) driven by a cam (21) and guided by a guide rocker (3). The guide rocker which is pivotably connected on the intermediate lever is connected to a fixed mounted positioning arm (64) coupled to a support component (6). The positioning arm with the connection of the guide rocker is installed in such a way that with an adjustment of the support component to reduce the valve lift the connection of the guide rocker pivots in the rotational direction (DR21) of the cam.
