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. Portions of the latch pin assembly are configured to move so that when the cam side rocker arm portion selectively rotates, the valve side rocker arm portion switches among a full lift mode, a partial lift mode, and a lost motion lift mode.
