Abstract
A rocker assembly for a type III center pivot valvetrain comprises a rocker arm having a cam end, a center pivot bore, and a valve end which includes a first actuator bore and a second actuator bore. The rocker assembly further comprises a cylinder deactivation actuator arranged in the first actuator bore. The cylinder deactivation actuator comprises a hydraulically actuated latch assembly configured to selectively switch between a latched configuration and an unlatched configuration and a mechanical lash-setting sleeve distanced from a travel stop defined within the first actuator bore. The cylinder deactivation actuator further comprises a latch step disposed below the mechanical lash-setting sleeve and extending into the first actuator bore. The hydraulically actuated latch assembly is configured to selectively travel between the travel stop and the latch step when the hydraulically actuated latch assembly is in the latched configuration.
