Abstract

A system for actuating at least one engine valve comprises an output rocker operatively connected to the at least one engine valve. A first rocker assembly is operatively connected to a first valve actuation motion source. The first rocker assembly comprises a first input rocker arranged in series with a first lost motion component, wherein the first input receives first valve actuation motions from the first valve actuation motion source and the first lost motion component is operatively connected to the output rocker. A second rocker assembly is operatively connected to a second valve actuation motion source. The second rocker assembly comprises a second input rocker arranged in series with a second lost motion component, wherein the second input rocker receives second valve actuation motions from the second valve actuation motion source and the second lost motion component is operatively connected to the output rocker.
