Abstract
The axes of the three inlet valves associated with each cylinder of an internal combustion engine are parallel to each other. The valves are all operated by the same camshaft which acts on the three valves from above through three interposed rocker arms. The rocker arm of the valve which is in the intermediate position is in a reverse orientation relative to the other two rocker arms.
