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 13):
A compression braking system for an internal combustion engine, comprising:\n a brake tappet that is configured to link at least one exhaust valve to an exhaust cam, the exhaust cam including a brake bump portion and an exhaust lobe, the brake tappet including:\n a housing extending along a longitudinal axis; \n a lash assembly in an interior of the housing, the lash assembly being longitudinally movable relative to the housing; \n first and second locking pins in the housing movable relative to the lash assembly to selectively fix and release the lash assembly relative to the housing, wherein in a non-compression braking mode the locking pins are positioned so the lash assembly is longitudinally movable relative to the housing to absorb the brake bump portion acting on the brake tappet without transferring the brake bump portion to the at least one exhaust valve and the lash assembly is movable with the housing in response to the exhaust lobe acting on the brake tappet to transfer the exhaust lobe to the at least one exhaust valve; and \n in a compression braking mode the lash assembly is fixed relative to the housing so that the brake bump portion and the exhaust lobe of the exhaust cam are each transferred to the at least one exhaust valve.
