摘要： 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.

摘要： A valve actuation system comprises a valve actuation motion source configured to provide main and auxiliary valve actuation motions for actuating at least one engine valve via a valve actuation load path. A lost motion subtracting mechanism is arranged in a valve bridge and configured, in a first default operating state, to convey at least the main valve actuation motion and configured, in a first activated state, to lose the main valve actuation motion and the auxiliary valve actuation motion. Additionally, a lost motion adding mechanism is arranged in a rocker arm and configured, in a second default operating state, to lose the auxiliary valve actuation motion and configured, in a second activated state, to convey the auxiliary valve actuation motion, wherein the lost motion adding mechanism is parallel with the lost motion subtracting mechanism in the valve actuation load path at least during the second activated state.
