ABSTRACT:
A valve operating mechanism for internal-combustion engines has a valve and a pressure spring which is to move the valve into a closed end position and which is supported on a spring plate. For the reduction of the valve operating masses, at least the valve, the pressure spring and the spring plate are optimized with respect to their weight. The spring plate consists of a plastic material and has widenings of the cross-section for absorbing the occurring stresses.
