<p>The invention relates to an inlet and exhaust valve arrangement (3) for an internal combustion engine with a valve disc (4) which has at least a passage opening (6) and is arranged drivable by a shaft (7) in a rotating manner in a cylinder head (5), wherein the cylinder head (5) has a valve seat (8) assigned to the top of the valve disc (4, 4a, 4b) and at least a port which, during a rotational movement of the valve disc (4), is cyclically exposed and closed again by at least one passage opening (6) and wherein the valve disc (4) and the valve seat (8) starting from the shaft (7) run in a curved or taper angled way in the direction of the bottom of the valve disc (4) . According to the invention the valve disc (4) is elastically bendable whereby during the rotational movement the valve disc (4) is deflected and the edge of the valve disc (4) is moved in the direction of the valve seat (8), defining a self-sealing valve arrangement.</p> |
