ABSTRACT:
An internal combustion engine having a plurality of intake and/or exhaust valves associated with each cylinder includes a valvetrain having a fulcrum with a plurality of pivot ball sockets each associated with a rocker arm and pivot ball disposed between the fulcrum and the rocker arm with the fulcrum extending through apertures of the rocker arms and having a plurality of slots, each slot having generally parallel opposing lateral surfaces for receiving and guiding both sides of an associated rocker arm so the rocker arm pivots about the pivot ball in a plane of the rocker arm. The fulcrum can accommodate at least two rocker arms that may operate in non-parallel planes relative to one another and can include bearing and locating surfaces integrally formed to finish dimensions to eliminate machining.
