Valve train control apparatus and method for installing valve train control apparatus

The present invention relates to a valve train control apparatus and a method for installing the valve train control apparatus. In terms of the valve train control apparatus,the maximum valve lift of a first valve of a first valve group and the maximum valve lift of a second valve of a second valve group operated by a camshaft are assigned to a valve switching element with an internal combustion engine by a via variable valve train. The switching element is switchable between a first switching position and a second switching position, and produces the maximum first valve lift in the first switching position and the second maximum valve lift in the second switching position. The valve train control device has: an axially movable first push element for changing the switching position of the valve lift of the first valve group by manipulating motion conversion; an axially movable second push element for changing the switching position of the valve lift of the second valve group by switching the steering movement
