摘要： A gas exchange valve of an internal combustion engine may include a hollow valve stem and a valve disc. The valve disc may include a valve bottom and a hollow valve cone which is connected to an outer edge of said valve bottom. The hollow valve cone may taper with increasing distance from the valve bottom. The valve stem may pass through the hollow valve cone. The valve stem may be fixedly connected on the one hand to the valve bottom and on the other hand to the tapered end of the valve cone. The valve stem may include a first hollow space which is fluidically separated from a second hollow space arranged in the valve disc. The first hollow space and the second hollow space may have a different cooling agent filling level.
