Title: Valve actuating mechanism for internal combustion engine

Abstract

This patent describes an internal combustion engine comprising a cylinder having a bore, a cylinder head fixed relative to the cylinder, and three poppet type valves supported by the cylinder head for reciprocation about respective axes all positioned on the same side of a plane containing the axis of the cylinder bore. It also comprises a single camshaft having three respective cam lobes each associated with a respective of the valves, the camshaft being rotatable about an axis extending parallel to the plane and lying on the same side thereof as the valve axes. A rocker arms means is associated with one of the cam lobes for operating its associated valve, and means is included for directly operating the remainder of the valves from the remaining cam lobes.
