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.

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, the rocker arm comprising:
- a rocker arm body configured to rotate about a rocker shaft, the rocker arm body comprising:
- a first event rocker arm assembly comprising a hydraulic capsule in a bore;
- and
- a second event rocker arm assembly,
- wherein the hydraulic capsule is configured to selectively engage the valve bridge assembly to open the first and second engine valves.
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, the rocker arm comprising:
- a rocker arm body;
- a first event rocker arm assembly formed in the rocker arm body and having a hydraulic lash adjuster (HLA) assembly integrated with a lost motion mechanism;
- and
- a second event rocker arm assembly formed in the rocker arm body,
- wherein the HLA assembly is configured to selectively engage a valve bridge assembly to open the first and second engine valves,
- wherein the second event rocker arm assembly is configured to selectively engage the valve bridge assembly to open only the second engine valve.
A method of manufacturing 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, the method comprising:
- providing a rocker arm body configured to rotate about a rocker shaft, the rocker arm body including a first event rocker arm assembly and a second event rocker arm assembly;
- and
- providing a hydraulic capsule in a bore formed in the first event rocker arm assembly;
- wherein the hydraulic capsule is configured to selectively engage the valve bridge assembly to open the first and second engine valves.
