Abstract
A valve operating mechanism includes a camshaft rotatable in synchronism with rotation of an internal combustion engine and having a plurality of cams of different cam profiles. First, second, and third rocker arms are held in sliding contact with the cams, respectively, for operating the valves according to the cam profiles of the cams. The rocker arms are selectively interconnected and disconnected by first and second selective couplings to operate the valves at different valve timings in low, medium, and high speed ranges of the internal combustion engine.
