摘要： A valve operating device for operating an intake or exhaust valve in an internal combustion engine includes a cam C having a cam profile including a valve lifting portion C for applying a force to open the engine valve and a base circle portion Cb for allowing the valve to be opened, the cam profile having a valve opening point P 2 and a valve closing point P 1 between the valve lifting portion and the base circle portion, a cam follower 10 slidably engaging the cam, and a hydraulic lash adjuster 9 combined with the cam follower for eliminating any gap between the means and the engine valve. The base circle portion has a gradient cam surface or a combination of different gradient cam surfaces for canceling out valve-lifting radial displacement of the base circle portion.
