Abstract

See full text

A valve actuation system comprises a first rocker assembly operatively connected to a first valve actuation motion source and to a first engine valve, with a first lost motion component arranged in series between 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, with a second lost motion component arranged in series between a second input rocker and a second output rocker. A one-way coupling mechanism is disposed such that the second valve actuation motions are transferred to the first output rocker, but the first valve actuation motions are not transferred to the second output rocker. Furthermore, a primary hydraulic lash adjuster is configured in the second rocker assembly such that the primary hydraulic lash adjuster operates upon the first output rocker via the one-way coupling mechanism.
