Abstract
Systems and methods for actuating engine valves are disclosed. The systems may include a rocker arm having an adjustable length push tube mounted to a first end and multiple contact surfaces for an engine valve bridge at a second end. An actuator piston assembly may be provided in the rocker arm between the first and second rocker arm ends. The actuator piston assembly is adapted to extend from the rocker arm under the influence of hydraulic pressure and actuate an inboard engine valve through the engine valve bridge when an actuator piston is locked into an extended position.
