Abstract: A compression-release brake system for effectuating a compression-release engine braking operation in connection with an internal combustion engine. The system includes a lost motion exhaust rocker assembly including a rocker arm, an actuation piston slidably received by the rocker arm to define part of a piston cavity in the rocker arm and movable between a piston retracted position and a piston extended position, the actuation piston configured to operatively associate with the exhaust valve to permit unseating of the exhaust valve from the seated state, and a reset device received by the rocker arm and operatively associated with the actuation piston to return the exhaust valve to the seated state by the end of the expansion stroke in the brake-on mode.

Abstract: A compression-release brake system comprises an exhaust rocker arm, an actuation piston slidable in a piston bore in the exhaust rocker arm so as to press an exhaust valve, a supply conduit formed within the exhaust rocker arm, and an exhaust valve reset device mounted to the exhaust rocker arm. The actuation piston defines an actuation piston cavity within the actuation piston bore between the piston bore and the actuation piston. The exhaust valve reset device includes a reset check valve disposed between the supply conduit and the actuation piston cavity to hydraulically lock the actuation piston cavity by closing the reset check valve when a pressure of the hydraulic fluid within the actuation piston cavity exceeds the pressure of the hydraulic fluid in the supply conduit. The reset check valve is biased closed by the pressure of the hydraulic fluid within the actuation piston cavity during the brake-on mode.
