Abstract
The present invention relates to a device () for shutting down at least one cylinder of an internal combustion engine. The device () is connected to a rocker lever () which actuates an intake/exhaust valve () of the respective cylinder. 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 ().
