A valve bridge for a rocker arm assembly, the valve bridge comprising:
- a first end, a second end opposite to the first end, and a top surface of a bridge body portion connecting the first and second ends, wherein the top surface of the bridge body portion is configured to engage with a first rocker arm;
- a first recess disposed at a top of the first end, wherein the first recess is configured to engage with a second rocker arm;
- a first valve seat disposed at a bottom of the first end and having a curved bottom surface to engage a first valve;
- and
- a second valve seat disposed at a bottom of the second end to engage a second valve;
- wherein the valve bridge is configured to:
- translate vertically upon actuation by the first rocker arm to actuate both the first and second valves, or
- tilt angularly upon actuation by the second rocker arm to actuate the first valve without actuating the second valve.
A valve bridge for a rocker arm assembly, the valve bridge comprising:
- a first end, a second end opposite to the first end, and a top surface of a bridge body portion connecting the first and second ends, wherein the top surface of the bridge body portion is configured to engage with a first rocker arm;
- a protrusion disposed at a top of the first end and configured to engage with a second rocker arm;
- a first valve seat disposed at a bottom of the first end and having a curved bottom surface to engage a first valve;
- and
- a second valve seat disposed at a bottom of the second end to engage a second valve,
- wherein the valve bridge is configured to:
- translate vertically upon actuation by the first rocker arm to actuate both the first and second valves, or

- a first rocker arm and a second rocker arm;
- a first valve and a second valve;
- and
- a valve bridge configured to be selectively actuated by the first rocker arm or the second rocker arm, the valve bridge comprising:
- a first end, a second end opposite to the first end, and a top surface of a bridge body portion connecting the first and second ends, wherein the top surface of the bridge body portion is configured to engage with the first rocker arm;
- a recess disposed at a top of the first end, wherein the recess is configured to engage with a spherical end of the second rocker arm;
- a first valve seat disposed at a bottom of the first end and having a curved bottom surface to engage the first valve;
- and
- a second valve seat disposed at a bottom of the second end to engage the second valve,
- wherein the valve bridge is configured to:
- translate vertically upon actuation by the first rocker arm to actuate both the first and second valves, or
- tilt angularly upon actuation by the second rocker arm to actuate the first valve without actuating the second valve.
