Abstract

A system for actuating at least two engine valves comprises a first rocker assembly operatively connected to a first valve actuation motion source and to a first engine valve. The first rocker assembly comprises a first lost motion component arranged in series with a first input rocker and a first output rocker. A second rocker assembly is operatively connected to a second valve actuation motion source and to a second engine valve. The second rocker assembly comprises at least one second rocker. The system further comprises a one-way coupling mechanism disposed between the first output rocker and the at least one second rocker such that second valve actuation motions are transferred from the at least one second rocker to the first output rocker, and first valve actuation motions are not transferred from the first output rocker to the at least one second rocker.
