Abstract
The invention relates to a valve train for internal combustion engines, comprising a camshaft and valve actuation elements for one or more valves, the elements being located in the cylinder head. The aim of the invention is to provide a valve train for an internal combustion engine, with which a reliable stroke adjustment of the valves can be made, without the need for complex technical resources, while at the same time allowing a forward or rear displacement of the valve orifice region. To achieve this, in order to modify the valve stroke curve, the contact point between the transfer member and the cam can be displaced along the periphery of the cam and the contact point between the transfer member and a control curve of the support body can be displaced, forcing the part of the transfer member that interacts with the cam to be guided, by shifting the transfer member in relation to the camshaft.
