    Abstract: A continuously variable valve lift mechanism for an internal combustion engine includes a cam, a cam follower, a valve follower, a rocker shaft, and a rocker arm. The cam follower includes a first roller driven by the cam and a second roller. The valve follower includes a driven face in contact with the second roller of the cam follower and a driving face. The rocker shaft contacts the valve follower. Rotational movement of the rocker shaft about a rocker shaft rotational axis results in movement of the driven face with respect to the second roller. The rocker arm has a pivot axis and is in contact with the driving face of the valve follower.
