1. A valve train arrangement comprising:
a rocker arm having a first end and a second end, the second end cooperating with a first valve;
a deactivating hydraulic lash adjuster (HLA) capsule cooperating with the first end of the rocker arm;
a lost motion spring (LMS) capsule having a housing that receives a lost motion spring, the LMS capsule located in a position on the valve train arrangement that is offset from the HLA capsule;
a lever arm configured between the HLA capsule and the LMS capsule wherein 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, wherein the LMS capsule further includes a spring cap that bears against an extension lobe of the lever arm; and
a lever pin received by the LMS capsule housing wherein during movement of the lever arm, the lever arm rotates about the lever pin allowing the spring cap to translate within the LMS capsule housing wherein the lever arm has a first end that is disposed against the HLA capsule and a second end coupled to the LMS capsule housing at the lever pin, wherein the extension lobe is positioned intermediate the first and second ends of the lever arm.
