Abstract
In one embodiment, a rocker arm assembly configured for variable valve actuation includes at least one rocker arm, a first valve and a second valve, a valve bridge configured to be actuated by the at least one rocker arm and including a first opening and a second opening for respectively receiving the first valve and the second valve, and a retention assembly at least partially received by the first opening of the valve bridge. The retention assembly includes a push nut and a ring for supporting the push nut. The retention assembly is configured to retain the first valve when the first valve is inserted into the first opening so as to resist separation of the valve bridge from the first valve.
