Abstract:
A rocker arm assembly for use in a valve train carrier, the rocker arm assembly being rotatable around a rocker shaft supported by the valve train carrier based upon a lift profile provided on a cam that rotates with a camshaft, a rotation of the rocker arm assembly causing translation of a corresponding engine valve, includes: a rocker arm body having an opening that receives the rocker shaft, the rocker arm body further defining an oil supply channel; a capsule assembly disposed on the rocker arm body and that selectively communicates oil to and from the oil supply channel, the capsule assembly including: a plunger assembly having a plunger that selectively translates within a plunger chamber between an extended rigid position based upon the plunger chamber being pressurized with oil and a retracted non-rigid position based upon the plunger chamber being depressurized, the plunger moving move the engine valve.

Claim (Index 1):
A rocker arm assembly configured for use in a valve train carrier, the rocker arm assembly being rotatable around a rocker shaft supported by the valve train carrier based upon a lift profile provided on a cam that rotates with a camshaft, a rotation of the rocker arm assembly causing translation of a corresponding engine valve, the rocker arm assembly comprising:\n a rocker arm body having an opening that receives the rocker shaft, the rocker arm body further defining an oil supply channel; a capsule assembly disposed on the rocker arm body and configured to selectively communicate oil to and from the oil supply channel, the capsule assembly comprising:\n a plunger assembly having a plunger configured to selectively translate within a plunger chamber between an extended rigid position based upon the plunger chamber being pressurized with oil and a retracted non-rigid position based upon the plunger chamber being depressurized, the plunger being configured to move the engine valve toward an open position; and \n a shuttle assembly configured to move between a first position and a second position based upon oil communicated in the oil supply channel, the shuttle assembly having a shuttle valve configured to selectively move between a closed position and an open position, wherein in the open position oil flows into the plunger chamber; and \n wherein the rocker arm assembly is configured to sequentially move along a (i) a first valve lift profile wherein pressurized oil is communicated from the oil supply channel, the shuttle assembly being configured to move into the second position causing the shuttle valve to be opened, the pressure chamber to be pressurized, and the plunger to move to the extended rigid position, (ii) a reset valve lift profile wherein pressurized oil is not communicated from the oil supply channel, the shuttle assembly being configured to move into the first position, and (iii) a valve closing profile.
