Device for actuating at least one load change valve of an internal combustion engine

摘要

A device for actuating at least one load change valve of an internal combustion engine has at least one load change valve arranged in a cylinder head of an internal combustion engine wherein the load change valve has a valve shaft and a closing spring forcing the valve shaft into a closed position. A camshaft having cams is provided. Its axis of rotation is arranged such that it extends perpendicularly to a travel direction of the valve shaft. A transmission arrangement is positioned so as to be movable parallel to the travel direction of the valve shaft. It has a transverse member positioned between the camshaft and the valve shaft parallel to the camshaft and also has rollers positioned on the transverse member on opposite sides of the valve shaft. Each roller cooperates with one of the cams having identical contours. The cam movement of the cams is transmitted by the rollers onto the transverse member performing a linear movement, and the linear movement of the transverse member is transmitted onto the valve shaft. The transmission arrangement also has slides connected to opposed ends of the transverse member. The slides are moveably guided parallel to the travel direction of the valve shaft in the cylinder head.
