ABSTRACT:
A compression-release brake system for operating an exhaust valve of an engine during an engine braking operation. The compression-release brake system comprises a self-contained compression brake control module (CBCM) operatively coupled to the exhaust valve for controlling a lift and a phase angle thereof and a source of a pressurized hydraulic fluid. The CBCM includes a casing defining piston and actuator cavities, a slave piston mounted within the piston cavity, a check valve provided between a supply conduit and a slave piston chamber and a compression brake actuator disposed in the actuator cavity. The compression brake actuator includes an actuator element and a biasing spring. The actuator element selectively engages the check valve when deactivated so as to unlock the slave piston chamber, and disengages from the check valve when activated so as to lock the slave piston chamber. The actuator element is exposed to atmospheric pressure.
