ABSTRACT:
A valve mechanism for internal combustion engines of a type having a plurality of intake or exhaust valves for each cylinder is shown. A unique arrangement is applied to the valve mechanism for permitting the cam shaft to be positioned above the intake (or exhaust) valves. With the arrangement, the freedom in layout of an associated ignition spark plug in the engine is increased.
