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 35):
The compression-release brake system of  claim 33 , wherein the compression-release brake system is configured for installation on the internal combustion engine and operation in a brake-on mode so that:\n the lost motion exhaust rocker assembly is operatively associated with the reset device to cause, during the compression stroke, the reset trigger to be moved from the trigger extended position into the trigger retracted position by relative movement between the pivoting rocker arm and a stop member of the lost motion exhaust rocker assembly to compress the reset pressure control spring while maintaining the reset check valve in the closed position, the lost motion exhaust rocker assembly is operatively associated with the actuation piston to cause, during the compression stroke, the actuation piston in the piston extended position to exert sufficient force on the exhaust valve to unseat the exhaust valve, and the reset device is operatively associated with the actuation piston so that after unseating of the exhaust valve, and as the hydraulic pressure within the piston cavity decreases, the biasing force of the reset pressure control spring compressed by the reset trigger and the reset piston moves the reset check valve into the open position to thereby release a portion of the hydraulic fluid in the piston cavity through the reset communication port so that the closing force of the exhaust valve return spring resets the exhaust valve to the seated state by the end of the expansion stroke.
