Valve drive mechanism for internal combustion engine; device and method for grinding three-dimensional cams

摘要

Valve drive mechanism, in particular for an internal combustion engine having intake and exhaust valves radially disposed for each cylinder of the internal combustion engine, comprising at least one three-dimensional cam (6,11) adapted to press against a cam follower (10) obliquely to a moving direction of a cam face. The cam face comprises a plurality of lubricant collecting ground marks, wherein an oil film is provided between the three-dimensional cam and the cam follower.
