Abstract: An exhaust valve rocker arm assembly operable in a combustion engine mode and an engine braking mode includes: a rocker shaft that defines a pressurized oil supply conduit; a rocker arm that receives the rocker shaft and rotates around the rocker shaft, the rocker arm including a rocker arm oil supply passage defined in the rocker arm; a valve bridge for engaging a first exhaust valve and a second exhaust valve; a hydraulic lash adjuster assembly, disposed on the rocker arm, including a first plunger body movable between a first position and a second position; and a check valve, disposed on the rocker arm, including an actuator for selectively releasing pressure in the hydraulic lash adjuster assembly. In the engine braking mode, by rotation of the rocker arm the pressurized oil supply conduit is brought into fluid communication with the rocker arm oil supply passage.

Abstract: A dual body rocker arm for controlling a valve of a cylinder of an internal combustion engine includes: a first body; a second body; and a latching arrangement moveable to latch and unlatch the first body and the second body. The latching arrangement includes: a latch pin moveable between a first position in which the latch pin latches the first body and the second body together and a second position in which the first body and the second body are un-latched; and a lever mounted for pivotal motion relative to the first body, a first end of the lever contacting the latch pin, and a second end of the lever configured to contact an actuation arrangement. In use, when the actuation arrangement exerts a force on the second end of the lever, the lever pivots such that the first end of the lever exerts a force on the latch pin.

Abstract: A valve train assembly includes a valve bridge assembly. The valve bridge assembly includes: a valve bridge; a first cavity formed towards a first end portion of the valve bridge; and a hydraulic lash adjuster (HLA) disposed within the first cavity, the HLA for engaging a first valve stem. The valve train assembly further includes: a pivotally mounted first rocker arm for engaging the valve bridge and to pivot in response to a rotating first cam to cause a first valve lift event in an engine cycle. The first rocker arm includes: a rocker arm cavity formed within an end portion thereof; and a control capsule disposed within the rocker arm cavity, wherein the control capsule is configurable in an ON configuration and an OFF configuration.

Abstract: A type II valve train assembly that selectively opens first and second intake valves and first and second exhaust valves is provided. The valve train assembly includes an intake rocker arm assembly and an exhaust rocker arm assembly. The valve train assembly is configurable for operation in any combination of activated and deactivated states of engine braking and cylinder deactivation. The exhaust rocker arm assembly includes a first exhaust rocker arm, a second exhaust rocker arm and an engine brake exhaust rocker arm. A first exhaust HLA is associated with the first exhaust rocker arm. A second exhaust HLA is associated with the second exhaust valve. An exhaust actuation assembly selectively actuates to alter travel of the first and second exhaust HLA's to change a state of cylinder deactivation between activated and deactivated.

Abstract: An actuator for actuating valve-lift modes of a valve train assembly of an internal combustion engine. The valve train assembly is capable of being switched between a first valve-lift mode and a second valve-lift mode. The actuator includes a first body and a second body. The second body is mounted for reciprocal movement with respect to the first body between a first position to cause the first valve-lift mode and a second position to cause the second valve-lift mode. The actuator includes a third body supported by the second body, the third body for moving a first component of the valve train assembly to cause the second valve-lift mode. The third body is moveable relative to the second body. The actuator includes a first biaser for biasing the third body away from the second body towards the first component of the valve train assembly.
