A valve system for internal combustion engines that is controlled by a camshaft is a potential source of engine damage if the timing thereof is disrupted (e.g. when the timing belts rupture). Furthermore, valves in combination with the camshaft and the timing chain contribute to noise and vibrations during operation. The production costs can be high. Thus, the engine is positioned higher and is heavier. Thus, there is proposed a valve mechanism composed of a plurality of gas exchange valves that revolve slowly about the cylinder wall. Each rotary valve is controlled separately and has symmetrical openings. The number of openings in the rotary valve corresponds to the number of working cycles per revolution. Since each rotary valve is driven separately and as a result of the size of the openings in the valve, it is possible to obtain different phase shifts, valve overlaps and opening times.

Valve apparatus for an internal combustion engine, which consists of at least two independent ring-like rotary valves, which rotate in contact-free manner against one another, about their axis, which is the same as the cylinder axis, and sit lined up one on top of the other on the outside around the cylinder wall, above the top dead point of the piston, wherein the rotary valves and the valve seats have openings disposed symmetrically relative to the axis of rotation, and a slanted section on the entire lateral slide surfaces, and the speed of rotation of each rotary valve for a work cycle can be slowed down by means of increasing the number of openings, and wherein the rotary valves are controlled separately from one another, in order to implement the phase shift.
