Valve operating mechanism for internal combustion engine, has springs supported at roll axis, which is pressed against operating force during passage of plateau areas opposite to radial cam directed in rotating direction of cams

摘要

The mechanism has a connecting link guided to a lever for actuating a gas-exchange valve (2), where the lever is supported in a cylinder head. Springs (6) are supported at a roll axis of the roll that stands in contact with cams, where force of the spring is measured such that the roll axis is pressed against the operating force during passage of plateau areas opposite to a radial cam (42) directed in the rotating direction of cams.
