Abstract
A rocker arm assembly for an engine valve system includes a rocker arm for actuating an engine valve, a stop, a biaser, and a swing lock attached to one of the valve end or the cam end of the rocker arm and defining a pivot axis, and including an actuating surface. The actuating surface is rotatable between a stopped orientation and an idled orientation, and the biaser biases the swing lock towards the stopped orientation where the swing lock contacts the stop and traps the swing lock between the rocker arm and one of an engine valve or a cam. The swing lock is movable in opposition to a bias of the biaser toward the idled orientation to deactivate the engine valve.
