Abstract
A rocker arm assembly to provide either cylinder deactivation or reduced valve lift. The rocker arm assembly includes inner and outer portions that are rotatably connected to one another. In one state, the inner and outer portions are locked together to provide traditional valve lift. In a second state, the inner portion is allowed to rotate relative to the outer portion to deactivate the cylinder or provide reduced valve lift. Bearings on both the inner and outer portions provide rolling contact with corresponding cam shaft features. A hydraulic system provides transition between the first and second states.
