Abstract:
A valvetrain assembly comprises a deactivatable rocker arm where a pushrod is configured to transfer a valve lift profile through to a valve end to a valve or valve bridge. A castellation assembly in a carrier and alternative two-piece rocker arm assemblies with rotary or linear actuators are shown for deactivating the transfer of the valve lift profile.
