Abstract
A variable valve actuation system to actuate and control the seating velocity of an internal combustion engine valve is disclosed. The system may comprise a rocker arm that includes first, second and third contact surfaces. The first contact surface may contact the engine valve. A hydraulic lost motion system may contact the rocker arm at the second contact surface, and a mechanical valve train element may contact the rocker arm at the third contact surface. The lost motion system may include a slave piston with a valve seating device incorporated therein. The lost motion system and the mechanical valve train element may be provided side by side at the end of the rocker arm opposite that of the engine valve.
