Abstract
A mechanically controllable valve operating mechanism includes a cylinder head, a camshaft, a transmission arrangement mounted to move in the cylinder head via a bearing device. A gas exchange valve has the transmission arrangement act thereon. A valve-lift adjusting device comprises a rotatable adjusting element with an eccentric element having two base points and a peak contour, and at least one further eccentric element. The valve-lift adjusting device acts on the transmission arrangement so that different valve-lift positions are settable. The transmission arrangement is connected to the valve-lift adjusting device and to the camshaft. The at least one further eccentric element of the rotating adjusting element is arranged so that at least two peak contours are provided so that, depending on a rotational angle α of the rotating adjusting element, the eccentric element or the at least one further eccentric element engage with the transmission arrangement.
