COMPRESSION BRAKE SYSTEM FOR AN ENGINE

摘要

A compression brake system (12) of an internal combustion engine (10) includes a mechanical system (110) for coupling a camshaft (36) to a brake actuator assembly (90). The mechanical system (110) includes a stationary housing (112) defining an aperture (124) and a lifter (130) is slidably disposed in the aperture (124). A resilient element is disposed between the housing (112) and the shoulder (128) and configured to bias the lifter (130) toward the camshaft (36). The mechanical system (110) is dedicated to compression braking, and therefore the camshaft (36) may have a lobe (38) optimized for braking.
