Abstract: Generally, a rotatable valve assembly operative in an internal combustion engine is provided. The rotatable valve assembly may comprise a valve body rotatably supported in the cylinder head. The valve body may have various shapes which may allow to maximize an effective working area of a combustion chamber head and at the same time to decrease an overall space occupied by a cylinder head of the engine. The rotatable valve assembly may directly utilize an engine's camshaft rotational motion to drive the rotational motion of the valve body, thereby eliminating a need in dedicated mechanisms that convert the camshafts rotational motion into linear translational motion typically utilized in current cylinder heads. Finally, rotational motion of the valve body may reduce a time required to reach a maximal effective working area for air-fuel mixture supply and/or gas exhaust and/or may provide a smoother and quitter engine operation.
