  • Systems and methods for hydraulic lash adjustment in an internal combustion engine
    Patent number: 9200541
    Abstract: Systems and methods for actuating engine valves for positive power and engine braking operation are disclosed. The systems may include a self-lashing hydraulic piston slidably disposed in a fixed or rocker arm housing. The hydraulic piston may have an internal cavity in which a motion absorbing piston is disposed. A hydraulic fluid source may communicate with the hydraulic piston bore. A check valve which may be incorporated in a control valve may controls hydraulic fluid supply from the hydraulic fluid source to the hydraulic piston to provide self-lashing operation of the valve actuation system.
    Type: Grant

  • Integrated lost motion rocker brake with automatic reset
    Patent number: 9016249
    Abstract: Systems and methods for actuating engine valves are disclosed. The systems may include a rocker arm having an adjustable length push tube mounted to a first end and multiple contact surfaces for an engine valve bridge at a second end. An actuator piston assembly may be provided in the rocker arm between the first and second rocker arm ends. The actuator piston assembly is adapted to extend from the rocker arm under the influence of hydraulic pressure and actuate an inboard engine valve through the engine valve bridge when an actuator piston is locked into an extended position.
