Abstract: A switching rocker arm comprises an outer arm having a pair of integrally formed axles extending outwardly therefrom and an inner arm pivotally secured to the outer arm. A is latch slidably connected to the outer arm and is configured to selectively extend to engage the inner arm. An inner roller is configured on the inner arm, and a pair of outer rollers is mounted on the respective integrally formed axles on the outer arm. A rocker arm for variable valve lift comprises an outer arm comprising outer arm portions, rollers mounted in a cantilevered manner to the outer arm portions, and an inner arm seated between the outer arm portions, the inner arm comprising an inner roller. A pivot axle connects the outer arm and the inner arm. The inner arm and the outer arm are pivotable with respect to one another about the pivot axle.

Abstract: A rocker arm assembly operable in a first mode and a second mode, the rocker arm assembly selectively opening first and second engine valves based on rotation of a cam shaft having a first cam lobe and a second cam lobe, includes: a rocker shaft; a first rocker arm assembly having a first rocker arm that receives the rocker shaft and rotates around the rocker shaft in the first mode based on engagement with the first cam lobe; a second rocker arm assembly having a second rocker arm that receives the rocker shaft and rotates around the rocker shaft and selectively act on one of the first and second engine valves in the second mode based on selective engagement with the second cam lobe; and a biasing assembly that cooperates with the second rocker arm to bias the second rocker arm to a neutral position.

Abstract: A valve train assembly includes at least a number of exhaust valves; at least one camshaft with at least a pair of a primary lift cam and an engine brake lift cam. A number of rocker arms each include a cam follower for following one of the primary lift cam and the engine brake lift cam. One rocker arm includes a cam follower following an engine brake lift cam. The rocker arm is provided with an engine brake capsule. Various biasing assemblies are disclosed that cooperate with one of the rocker arms of which the cam follower follows an engine brake lift cam to accommodate mechanical lash.

Abstract: An engine brake rocker arm assembly is operable in an engine drive mode and an engine braking mode and selectively opens first and second exhaust valves. The engine brake rocker arm assembly includes an exhaust rocker arm configured to rotate about a rocker shaft, 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, and a hydraulically controlled actuator assembly configured to selectively move the engine brake capsule assembly between the first and second positions.
