Abstract:
A compression-release brake system is provided that includes a lost motion exhaust rocker assembly, an actuation piston, and a reset device. The actuation piston includes an actuation piston body that is slidably received by the rocker arm to define a piston cavity in the rocker arm and is movable between piston retracted and extended positions. The actuation piston is configured to be operatively associated with the exhaust valve to permit unseating of the exhaust valve from the seated state. An actuation piston check valve is configured to move between closed and open positions to permit hydraulic fluid flow through an actuation piston communication port to the piston cavity. The reset device includes a reset check valve and a reset pressure control spring for applying a biasing force to the reset check valve to urge the reset check valve toward an open position.

Claim (Index 39):
An internal combustion engine, comprising:\n an engine cylinder associated with a four-stroke piston cycle comprising a compression stroke and an expansion stroke and provided with at least one intake valve, at least one exhaust valve, and at least one exhaust valve return spring exerting a closing force on the exhaust valve to urge the exhaust valve into a seated state; and the compression-release brake system of  claim 37 .
