Abstract:
A valvetrain assembly comprises a valve bridge, a capsule, a first rocker arm, and a second rocker arm. The valve bridge comprises an upper surface comprising a central pressure point and an offset pressure point and a lower surface comprising a lower pivot point, a first valve interface, and a second valve interface. The capsule can be connected to the lower pivot point, the capsule configured to provide to the pair of engine valves one or both of a lash adjusting function and a deactivating mode. The first rocker arm is configured to actuate against the central pressure point to transfer a first valve lift mode to the valve bridge. The second rocker arm is configured to actuate against the offset pressure point to transfer a second valve lift mode to the valve bridge.
