Abstract
A valve actuating mechanism for an internal combustion engine is provided including an integrally formed stop element to limit the axial travel of the valves toward the piston to a predetermined maximum extent in the event an adjacent associated valve becomes stuck and unmovable. The present invention further provides a valve actuating mechanism including a guideless valve bridge with specifically configured contact faces which prevents both the excess axial movement of the valve stem and the transfer of undesired loads to the valve stem or adjacent structures.
