Abstract
An inlet and exhaust valve arrangement for an internal combustion engine with a valve disk has at least one passage opening and is arranged in a cylinder head drivable by a shaft in a rotating manner and having a valve seat assigned to a top of the valve disk and at least a port that during rotation of the valve disk is cyclically exposed and closed again by at least one passage opening. The valve disk and the assigned valve seat starting from the shaft run in curve or taper at an angle toward a bottom of the valve disk. The valve disk is elastically bendable such that during rotation the valve disk is deflected and an edge of the valve disk is moved toward the valve seat to define therewith a self-sealing valve arrangement.
