Abstract
A compression brake system of an internal combustion engine includes a mechanical system for coupling a camshaft to a brake actuator assembly. The mechanical system includes a stationary housing defining an aperture and a lifter is slidably disposed in the aperture. A resilient element is disposed between the housing and the shoulder and configured to bias the lifter toward the camshaft. The mechanical system is dedicated to compression braking, and therefore the camshaft may have a lobe optimized for braking.
