Variable valve timing mechanism

A variable valve timing mechanism for controlling at least one biased valve comprising

• a. guide assembly having a mounting surface and a spaced apart upper guide surface, said assembly including support members and spaced apart longitudinal guides supported by support members,
• b. a closing stop mounted to said mounting surface having and a stop surface;
• c. an opening stop having a stop surface;
• d. a valve activator movably positioned within said guide assembly and in operable contact with said biased valve, said valve activator having first and second stop surfaces to contact a respective closing stop and opening stop and including first and second offset, continuing surfaces, and an angled contact surface positioned therebetween;
• e. a drive ram movably positioned within said guide assembly and in contact with said upper guide surface and said valve activator, said drive ram having a first and second offset, continuing surface, and an angled drive surface positioned therebetween for contacting said valve activator, and
• f. a drive connected to said drive ram for imparting reciprocating motion thereto, said drive being synchronized with the operation of said valve.
