Abstract
A rocker arm assembly comprises a valve side rocker arm portion, a cam side rocker arm portion configured to selectively rotate relative to the valve side rocker arm portion, and a latch pin assembly disposed in the valve side rocker arm portion and in the cam side rocker arm portion. A latch pin assembly is disposed for selective switching in the valve side latch bore and in the cam side latch bore. At least a portion of the latch pin assembly is configured so that when the latch pin assembly is selected to switch from a latched condition to the unlatched condition, and when the cam side rocker arm portion selectively rotates, the latch pin assembly is configured to retract from the forces of the rotation.
