Cam link variable valve mechanism

A variable valve mechanism, comprising:

• a unitary elongate input shaft having a plurality of opening cam lobes and a plurality of closing cam lobes, each one of said plurality of opening cam lobes being paired with a corresponding one of said plurality of closing cam lobes;
• a plurality of rocker assemblies, each of said plurality of rocker assemblies having a respective first end and a respective second end, each of said plurality of rocker assemblies carrying a respective roller, each respective said roller engaging a corresponding one of said plurality of opening cam lobes;
• a plurality of first split frame member assemblies each pivotally mounted upon said input shaft, each of said plurality of first split frame member assemblies being pivotally coupled at a respective first end to a corresponding one of said plurality of rocker assemblies, each of said plurality of first split frame member assemblies configured for being pivotally coupled at a respective second end to a control shaft;
• a plurality of first split output cams pivotally mounted upon said input shaft;
• and
• a plurality of links pivotally coupling a respective one of said plurality of split output cams to said second end of a corresponding one of said plurality of rocker assemblies.

An internal combustion engine, comprising:

• a variable valve mechanism, said variable valve mechanism including:
• an elongate input shaft having a central axis, an opening cam lobe and a closing cam lobe disposed upon said input shaft, said opening cam lobe and said closing cam lobe having a predetermined angular relation relative to each other and relative to said central axis;
• a rocker assembly having a first end and a second end, said rocker assembly carrying a roller, said roller engaging said opening cam lobe;
• a first split frame member assembly pivotally mounted upon said input shaft, said first split frame member assembly being pivotally coupled at a first end to said rocker assembly, said first split frame member assembly configured for being pivotally coupled at a second end thereof to a control shaft;
• a first split output cam pivotally mounted upon said input shaft;
• and
• a link pivotally coupling said first split output cam to said second end of said rocker assembly.
