Abstract
An apparatus for limiting the travel of a slave piston (,) in a slave piston cylinder (,) in a compression release engine brake is disclosed. The apparatus provides stroke-limiting means and independent lash adjustment means which may be installed in a common rail, variable valve actuation system. The independent lash adjustment means comprises a sleeve (,) around the slave piston (,), threadably mounted in the brake housing (,). The stroke-limiting means comprises a slave piston (,) in a slave piston cylinder (,), a trigger valve (,) and a hydraulic circuit connected thereto. The slave piston stroke is limited when a lower flow port (,) in the slave piston cylinder (,) is opened to drain (,) slightly before high-pressure flow is cut off through an upper flow port (,) in the slave piston cylinder (,).
