Abstract (en)
[origin: WO2020099669A1] An exhaust valve rocker arm assembly operable in a drive mode and an engine braking mode includes a rocker shaft, a rocker arm (30), a hydraulic lash adjuster assembly (12), an accumulator assembly (16) and a locking pin (52). The rocker shaft (34) has an oil gallery defined thereon. The rocker arm (30) has an oil feed channel that is fluidly connected to the oil gallery. The rocker arm (30) further defines an engine brake relief hold and an accumulator relief hole (46). The accumulator assembly (16) is disposed in the rocker arm (30) and is fluidly coupled to the hydraulic lash adjuster through an engine brake relief hole (94). The locking pin assembly (20) is disposed in the rocker am (30) and is selectively movable by a high pressure fluid from a closed position to an open position.
