Compression brake for internal combustion engine

Abstract:

An engine compression braking system includes a brake tappet linking an exhaust cam to at least one exhaust valve of an engine cylinder. The brake tappet is connected with a working fluid that selectively activates and deactivates a compression braking mode of operation by selectively engaging and releasing a lash assembly of the brake tappet relative to a housing of the brake tappet.
