Abstract: A rocker arm has a first roller for engaging a first rotatable cam surface, whereby at least part of the rocker arm can be pivoted by at least the first rotatable cam surface to move a valve to cause a first valve event, and a further roller for engaging a further rotatable cam surface, whereby at least part of the rocker arm can be pivoted by the further rotatable cam surface to move the valve to cause a second valve event which is different from the first valve event. The rocker arm is configurable in a first mode of operation in which one of the first and second valve events occur and a second mode of operation in which both the first and second valve events occur or the other of the first and second valve events occur.

Abstract: An exhaust valve rocker arm assembly operable in a combustion engine mode and an engine braking mode can include a rocker shaft and a rocker arm. The rocker shaft can define a pressurized oil supply conduit. The rocker arm can receive the rocker shaft and is configured to rotate around the rocker shaft. The rocker arm can have an oil supply passage defined therein. A valve bridge can engage a first exhaust valve and a second exhaust valve. In the engine braking mode, pressurized oil is communicated through the pressurized oil supply conduit, through the rocker arm oil supply passage and against an actuator such that a first plunger acts on the valve bridge during rotation of the rocker arm to a first angle opening the first valve a predetermined distance while the second valve remains closed.

Abstract: An arrangement for a valve train assembly in an internal combustion engine includes: a valve train component having a body that defines a bore with a first bore section and a second bore section, the first bore section having a diameter that is greater than a diameter of the second bore section; and a hydraulic lash adjustor having a plunger mounted for reciprocal sliding movement in the second bore section to enable the hydraulic lash adjustor to expand and contract, the hydraulic lash adjustor further including a first chamber and a second chamber. The first chamber is at least partly in the first bore section and can hold hydraulic fluid for flowing into the second chamber through a valve in response to the hydraulic lash adjustor expanding.
