Abstract: A rocker arm configured to perform a first event and a second event against a valve bridge assembly operably associated with first and second engine valves includes a rocker arm body configured to rotate about a rocker shaft. The rocker arm body includes a first event rocker arm assembly comprising a hydraulic capsule in a bore, and a second event rocker arm assembly. The first event rocker arm assembly is configured to selectively engage the valve bridge assembly to open the first and second engine valves.

Abstract: A combined exhaust and engine brake rocker arm assembly configured to selectively open first and second exhaust valves, includes a rocker arm body, an exhaust rocker arm assembly formed in the rocker arm body, and an engine brake rocker arm assembly formed in the rocker arm body and configured to operate in a collapse mode and a rigid mode. The exhaust rocker arm assembly is configured to selectively engage a valve bridge to open the first and second exhaust valves, and the engine brake rocker arm assembly is configured to selectively engage the valve bridge to open only the first exhaust valve.

Abstract: A valve train assembly includes a first exhaust valve, a second exhaust valve, and a valve bridge including a main body and a lever rotatably coupled to the main body, the main body configured to engage the first exhaust valve, and the lever configured to engage the second exhaust valve. An exhaust valve rocker arm assembly is configured to selectively open the first and second exhaust valves, the exhaust valve rocker arm assembly including an exhaust valve rocker arm with a hydraulic lash adjuster (HLA) assembly coupled thereto, the HLA assembly in contact with the valve bridge main body. An engine brake rocker arm assembly is configured to selectively open the second exhaust valve and including an engine brake rocker arm with a combined HLA and added motion capsule coupled thereto. The combined HLA and added motion capsule is configured to selectively engage and rotate the lever.
