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.

Claim (Index 1):
A compression braking system for an internal combustion engine, comprising:\n a cylinder housing a piston operably connected to a crankshaft, the cylinder further including at least one intake valve and at least one exhaust valve for selectively opening and closing respective ones of at least one intake opening and at least one exhaust opening of the cylinder; a camshaft including a first cam and a second cam, the first and second cams being rotatable with rotation of the camshaft, the first cam defining an inner base circle portion, a first cam lobe projecting from the inner base circle portion, and a brake bump portion projecting from the inner base circle portion, and the second cam defining a second base circle portion and a second cam lobe projecting from the second base circle portion; and a valve opening mechanism linking the first and second cams to respective ones of the at least one exhaust valve and the at least one intake valve, the valve opening mechanism including a brake tappet linking the at least one exhaust valve to the first cam, wherein in a non-compression braking mode the brake tappet is configured to absorb the brake bump portion in response to the brake bump portion being in contact with the valve opening mechanism without opening the at least one exhaust valve and to open the at least one exhaust valve in response to the first cam lobe being in contact with the valve opening mechanism, and in a compression braking mode the brake tappet opens the at least one exhaust valve in response to each of the brake bump portion and the first cam lobe being in contact with the valve opening mechanism.
