Mechanically controllable valve operating mechanism, and mechanically controllable valve operating mechanism arrangement

A mechanically controllable valve operating mechanism comprising:

• a cylinder head;
• a bearing device;
• a transmission arrangement comprising an end surface, the transmission arrangement being mounted so as to be movable in the cylinder head via the bearing device;
• a gas exchange valve configured to have the transmission arrangement act thereon via the end surface of the transmission arrangement;
• a spring element;
• a valve-lift adjusting device comprising a rotatable adjusting element with an eccentric element having two base points and a peak contour, and at least one further eccentric element arranged in a circumferential direction, the valve-lift adjusting device being configured to act on the transmission arrangement counter to a pre-stressing force of the spring element so that different valve-lift positions are settable;
• and
• a camshaft;
• wherein, the transmission arrangement is operatively connected to the valve-lift adjusting device and to the camshaft, and
• wherein, 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 a of the rotating adjusting element, the eccentric element or the at least one further eccentric element engage with the transmission arrangement.

A mechanically controllable valve operating mechanism arrangement comprising:

• a cylinder head;
• a bearing device;
• gas exchange valves arranged in a line;
• cylinders configured to be in-line, at least two of the gas exchange valves being assigned to each of the cylinders;
• a transmission arrangement assigned to each of the gas exchange valves, each transmission arrangement being mounted so as to be movable in the cylinder head via the bearing device;
• a spring element;
• a valve-lift adjusting device comprising at least one rotatable adjusting element with at least one eccentric element having two base points and a peak contour, the valve-lift adjusting device being configured to act on the transmission arrangement counter to a pre-stressing force of the spring element so that different valve-lift positions are settable;
• and
• a camshaft;
• wherein, each transmission arrangement is configured to be operatively connected to a respective valve-lift adjusting device and the camshaft, and
• wherein, at least one of the at least one rotatable adjusting element comprises at least one further eccentric element arranged along a circumferential direction so as to provide at least two peak contours so that, depending on a rotation angle α of the at least one adjusting rotatable element, the at least one eccentric element or the at least one further eccentric element engage with the transmission arrangement.
