Abstract
Valve control for at least one valve of an internal combustion engine, in which the movement of at least one cam (2) of a camshaft (3) can be transmitted to a valve stem (5) of the valve (1) by a transmission mechanism (4), the transmission mechanism (4) including at least one transmission element (7) which is mounted rotatably on an axis (6) and is preferably designed as a rocker arm (10) or drag lever and which is connected to the camshaft (3) via a contact element (8) arranged on the transmission element (7), the contact surface (19) of the contact element (8) and the circumferential surface (20) of the cam (2) having, at least in regions, curved and mutually corresponding contours in the axial direction (21), and the transmission element (7) being mounted axially moveably on an axial body (11) of the axis (6).
