Abstract: An inner and an outer valve can be designed with orbicular heads. The inner valve including a stem of a smaller outside diameter than the outer valve. The outer valve including a hollow stem large enough to accept the inner valve, and also including a valve seat in the centre of its bottom face to seat the inner valve. The head, or base, being equipped with one or more vents which communicate between the intake port and the combustion chamber and being releasably opened and sealed off by the inner valve. The vented valve unit incorporates an independent actuate by way of pressure differentials created by the inductors cycle, and and/or of directional inertia factors of the mechanically controlled valve element.
