Abstract
A rocker assembly includes a valve bridge, a guidepost, and a spring. The valve bridge is operably associated with the rocker assembly and configured to engage a first exhaust valve and a second exhaust valve. The valve bridge includes an internal chamber extending into the valve bridge from a bottom side of the valve bridge. The guidepost is at least partially disposed within the internal chamber. The guidepost is secured to a valvetrain carrier and extends upwards to the valve bridge. The valve bridge is configured to translate along the guidepost. The spring is disposed around the guidepost. A first end of the spring is disposed on a top surface of the valvetrain carrier, and a second end of the spring is disposed against the bottom side of the valve bridge.

A rocker assembly, comprising:
- an exhaust rocker arm configured to selectively open a first exhaust valve and a second exhaust valve;
- a valve bridge operably associated with the rocker arm assembly and configured to engage the first exhaust valve and the second exhaust valve, wherein the valve bridge comprises an internal chamber extending into the valve bridge from a bottom side of the valve bridge;
- a guidepost at least partially disposed within the internal chamber, wherein the guidepost is secured to a valvetrain carrier and extends upwards to the valve bridge, wherein the valve bridge is configured to translate along the guidepost;
- a spring disposed around the guidepost, wherein a first end of the spring is disposed on a top surface of the valvetrain carrier, and wherein a second end of the spring is disposed against the bottom side of the valve bridge;
- and
- a brake rocker arm configured to selectively open the second exhaust valve.
A valve assembly, comprising:
- a valve bridge configured to engage a first exhaust valve and a second exhaust valve, wherein the valve bridge comprises an internal chamber extending into the valve bridge from a bottom side of the valve bridge;
- the first exhaust valve secured in relation to the valve bridge;
- the second exhaust valve secured in relation to the valve bridge;
- a guidepost at least partially disposed within the internal chamber, wherein the valve bridge is configured to translate along the guidepost;
- and
- a spring disposed around the guidepost, wherein a first end of the spring is disposed on a top surface of a valvetrain carrier, and wherein a second end of the spring is disposed against the bottom side of the valve bridge.
A valvetrain assembly, comprising:
