    Abstract: An engine brake rocker arm assembly for a valvetrain and operable in an engine drive mode and an engine braking mode. The assembly is configured to selectively open one of first and second exhaust valves in the engine braking mode and includes a brake rocker arm configured to rotate about a rocker shaft, and an engine brake capsule assembly movable between (i) a locked position configured to perform an engine braking operation, and (ii) an unlocked position that does not perform the engine braking operation. A lash setting tool is configured to removably engage the engine brake capsule assembly and move the engine brake capsule to the locked position to enable mechanical lash adjustment while the brake rocker arm is assembled in a valvetrain and the engine brake capsule is assembled in the brake rocker arm.

    Abstract: A hydraulic capsule can comprise a hollow capsule body for setting the location of a plunger, a latch set alignable with a latch groove, and a latch-setting insert. The plunger can be configured to push the latch set towards the latch-setting insert. A lost motion spring can be incorporated into the hydraulic capsule, or the lost motion spring can be installed in capsule bore where the hydraulic capsule is mounted. Either a hydraulic capsule or an electromagnetic capsule or a drop in assembly can be installed in a capsule mount in a rocker arm to form a type III cam-actuated rocker arm. The rocker arm can comprise a cam side arm and a valve side arm. The rocker arm can be configured to balance a moment of inertia of the deactivation components. Twisting forces on the cam can be counteracted.

    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: A switching roller finger follower (SRFF) assembly for valve actuation comprises an outer arm, an inner arm, an inner roller, a bearing axle and a pair of outer rollers. The outer arm is pivotally coupled to a pivot axle. The inner arm is at least partially disposed within the outer arm and pivotally coupled to the pivot axle. The inner roller assembly comprise a bushing and an outer ring. The bushing defines a curved slot therein. The bushing is fixed to the inner arm. The outer ring is configured to rotate around the bushing. The bearing axle extends through the curved slot. The pair of outer rollers are disposed on each end of the bearing axle.
