Abstract:
A valve drive includes a transfer arrangement with an intermediate lever arrangement having a first roller element and an intermediate lever, and a drag lever arrangement having a drag lever. The first roller element is connected to a circumferential contour of a camshaft. The intermediate lever includes a second roller element and a working curve connected to the drag lever. A slotted guide is provided for the intermediate lever arrangement which is engaged by a guide roller element. A torsion spring element with first and second ends engages the intermediate lever arrangement. The first end rests on the cylinder housing portion. The second end acts on a counter bearing rigidly connected with the intermediate lever. The first and second roller element axes are arranged to introduce a force into the intermediate lever which presses the guide roller element against the slotted guide and the first roller element against the camshaft.
