Abstract:
In an internal combustion engine comprising two or more engine valves that receive valve actuation motions from a valve actuation motion source via a valve train, which valve train comprises a hydraulic lash adjuster, an apparatus for valve actuation comprises a valve bridge and a lost motion assembly disposed therein. The lost motion assembly comprises a first piston disposed in a first piston bore formed in the valve bridge. The first piston is configured to operatively connect with a component of the valve train. A biasing element is configured to bias the first piston out of the first piston bore with a first force that is greater than a second force applied to the first piston by the hydraulic lash adjuster. A travel limiter is configured to limit travel of the first piston out of the first piston bore to be no greater than a maximum lost motion distance.
