The invention relates to a method and to a device for opening and closing a valve of an internal combustion engine. The aim of the invention is to reduce the energy required for opening and closing a valve of an internal combustion engine, especially one that is provided with an electromagnetic valve control. To this end, the kinetic energy of the valve is transferred to a mass and temporarily stored in a mass.
