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 disposed between the first event rocker arm assembly and the rocker shaft in an axial direction of the rocker arm body,
- 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 configured to rotate about a rocker shaft, the rocker arm body comprising:
- a first event rocker arm assembly comprising a hydraulic capsule;
- and
- a second event rocker arm assembly comprising an engine brake capsule, the second event rocker arm assembly being disposed between the first event rocker arm assembly and the rocker shaft in an axial direction of the rocker arm body,
- wherein the hydraulic capsule is configured to selectively engage the valve bridge assembly to open the first and second engine valves,
- wherein the engine brake capsule is configured to selectively engage the valve bridge assembly to open only the second engine valve.
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, the hydraulic capsule having an outer plunger body and an inner plunger body;
- and
- a second event rocker arm assembly comprising an engine brake capsule, the second event rocker arm assembly being disposed between the first event rocker arm assembly and the rocker shaft in an axial direction of the rocker arm body,
- wherein the hydraulic capsule is configured to selectively engage the valve bridge assembly, via the inner plunger body, to open the first and second engine valves,
- wherein the engine brake capsule is configured to selectively engage the valve bridge assembly to open only the second engine valve.
