Type iii cam side cylinder deactivation

A rocker arm assembly for a valvetrain assembly, the rocker arm assembly comprising:

• a rocker arm configured to rotate about a rocker shaft and having a valve side end configured to selectively engage an engine valve, and a cam side end configured to be selectively engaged by a camshaft;
• and
• a cylinder deactivation (CDA) capsule coupled to the cam side end and comprising:
• an outer body having at least one slot formed therein, the outer body configured to be coupled to the rocker arm;
• and
• an inner plunger at least partially received within the outer body and having at least one outwardly extending tab, the inner plunger configured to translate within the outer body,
• wherein the at least one outwardly extending tab is received within the at least one slot and a groove formed in the rocker arm to facilitate preventing rotation of the inner plunger and outer body relative to the rocker arm, and
• wherein the CDA capsule is movable between an activated position where the CDA capsule is configured to transfer motion from the camshaft to the engine valve, and a deactivated position where the CDA capsule is configured to absorb the motion from the camshaft.
