A variable valve mechanism includes an elongate input shaft having a central axis. An input cam lobe is disposed on the input shaft and is eccentric relative to the central axis. A guide member is pivotally mounted on the input shaft. A frame is disposed in engagement with the input cam lobe, and is pivotally and slidably coupled to the guide member. A link has a first end pivotally coupled to the frame. An output cam is pivotally mounted on the input shaft. The output cam is pivotally coupled to a second end of the link arm. The output cam is configured for oscillating engagement of a roller of a roller finger follower.

Variable valve mechanism having an eccentric-driven frame

A variable valve actuating comprising a spring guide for use with a curved spring includes an elongate, curved guide member having a centerline. The centerline has a centerline curvature that is substantially equal to the radius of curvature of the curved spring. The guide member has a first side having a side curvature. The side curvature is substantially equal to a curvature of the curved inside surfaces of the coils of the curved spring. The guide member is configured for being disposed within the curved spring such that the coils thereof substantially surround a periphery of the guide member.
