Abstract: 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.

Abstract: A valvetrain assembly configured to selectively perform a bleeder brake operation includes a rocker arm configured to rotate about a rocker shaft, a camshaft having a lobe configured to impart motion to the rocker arm through a pushrod, and a valve bridge assembly operably associated with the rocker arm and configured to be selectively engaged by the rocker arm to open at least one of a first and second engine valve. An engine brake capsule is operably associated with the valve bridge assembly and configured to operate in a drive mode where the engine brake capsule does not cause the valve bridge assembly to open the first or second engine valves, and a brake mode where the engine brake capsule engages the valve bridge assembly to partially open the first engine valve to perform the bleeder brake operation.

Abstract: An engine system and valvetrain can comprise a rocker shaft combined with a first block, a first cylinder deactivation oil control valve in the first block, a second cylinder deactivation oil control valve in the first block. Also, a second block can be combined with the rocker shaft with a third cylinder deactivation oil control valve and an early exhaust valve opening oil control valve in the second block. The rocker shaft can comprise oil infeeds and oil outfeeds configured for supplying hydraulic pressure to the first and second blocks, the blocks can distribute the pressure to the control valves, and the blocks can return pressure to the rocker shaft. Intake and exhaust rocker arms can receive the returned pressure to actuate valves, and the rockers arms can be arranged line-to-line with no overlap during motion.

Abstract: Systems for valve actuation in internal combustion engines provide configurations for hydraulic lash adjusters and valve actuation valvetrain components that are particularly suitable for prevention of HL A jacking in lost motion cam environments and in valve bridge environments. In one implementation, a rocker arm may transmit motion from a lost motion cam having main event and auxiliary event lobes. Main event motion is transmitted to two engine valves through the rocker arm, a lash adjuster, lash adjuster loading component and valve bridge, which define part of a first load path. Braking motion is transmitted to one of the engine valves through an inboard valve actuator and bridge pin, which define part of a second load path. The HLA is thus disposed in a separate load path from the braking valve load and the lash adjuster loading component keeps the lash adjuster under a constant compressive force to prevent jacking.
