In active cylinder operation, the rocker lever () executes an oscillating tilting movement about a pivot axle () which is situated in the area of the connection to the cylinder head (), whereas when the respective cylinder is deactivated, the rocker lever () is lifted by the cylinder head () and therefore its pivot axle () is shifted in the direction of the connection of the rocker lever () to the valve of the respective cylinder. It is essential to the invention here that the device () is arranged essentially between the rocker lever () and the cylinder head () and the device has a guide element (), a pivot axle element () displaceably mounted on the guide element () and a spring () stretched between two abutments ().
