The valve control system for the continuous adjustment of the control times and strokes of the valves of an internal combustion engine has an eccentric shaft which is common to the intake and exhaust valves and is arranged in the cylinder head and which has for each cylinder a single eccentric for the driving of two connecting rods 4. The two connecting rods 4 form between their longitudinal axes an angle of less than 180 DEG and each of them drives a swing cam 6. For the positive control of the intake and exhaust valves respectively each swing cam is in engagement in both directions of swing in form-locked manner with the fork section of a valve rocker which is pivotally connected to the associated valve. The eccentric shaft is displaceable transversely to its longitudinal axis in a direction such that by a displacement of the eccentric shaft the distances between the eccentric and the axes of the two valve rockers are simultaneously decreased and increased respectively.
