Abstract
A valve train arrangement constructed in accordance to one example of the present teachings includes a rocker arm, a deactivating hydraulic lash adjuster (HLA) capsule, a lost motion spring (LMS) capsule and a lever. The rocker arm has a first end and a second end. The second end cooperates with a valve. The HLA capsule cooperates with the first end of the rocker arm. The LMS capsule has a lost motion spring. The LMS capsule is located in a position on the valve train arrangement that is offset from the HLA capsule. The lever is configured between the HLA capsule and the LMS capsule. During cylinder deactivation, load is transferred from the HLA capsule to the lever arm and ultimately to the lost motion spring in the LMS capsule.
