ABSTRACT:
A sealing arrangement for a ball-shaped or planar rotary valve of an internal combustion engine comprises a hollow sealing body mounted for rotation in a gas channel of the cylinder head and sealingly engaging the outside sealing surface of the rotary valve. A backside surface of the sealing body turned away from the combustion chamber is permanently exposed to the gas pressure therein in order to urge the sealing body inwards against the rotary valve with a sealing force dependent on the momentary gas pressure.
