    Abstract: Systems for valve actuation in internal combustion engines provide configurations for hydraulic lash adjusters and valve actuation valvetrain components that are particularly suitable for prevention of HLA jacking in lost motion cam environments and in valve bridge environments. In one implementation, a rocker arm may transmit motion from a lost motion cam having main event and auxiliary event lobes. Main event motion is transmitted to two engine valves through the rocker arm, a lash adjuster, lash adjuster loading component and valve bridge, which define part of a first load path. Braking motion is transmitted to one of the engine valves through an inboard valve actuator and bridge pin, which define part of a second load path. The HLA is thus disposed in a separate load path from the braking valve load and the lash adjuster loading component keeps the lash adjuster under a constant compressive force to prevent jacking.

    Abstract: A rocker arm comprising a supply path that communicates with a first lash bore and a first spool bore. A spool is in the spool bore. A hydraulic lash device is in the first lash bore, wherein an outer body is configured to collapse during a first valve lift profile when receiving a low pressure fluid, and wherein the outer body and the inner body are configured to cooperate rigidly when receiving a high pressure fluid during a second valve lift profile. The spool is movable to a first spool position to align the spool notch with a first spool path and a second spool path, and the spool is movable to a second spool position to align the spool notch with the second spool path and an accumulator path. The supply path in to the rocker arm is the only source of fluid to the spool.

    Abstract: An assembly clip for holding together a stationary hydraulic lash adjuster (SHLA) and a roller finger follower (RFF) in a valve train of an internal combustion engine (ICE) is provided. The SHLA has a pivot, and the RFF has a pivot cap configured to fit around the pivot. The assembly clip includes a first attachment section and a second attachment section configured to engage with the pivot cap and pivot, respectively, to attach the assembly clip to the RFF and SHLA, respectively. When assembled, the pivot and the pivot end are substantially located between the first attachment section and the second attachment section, the pivot cap covering at least a portion of the pivot. The assembly clip is made of an oil soluble material such that it may dissolve and break away after the valve train is assembled into the ICE, and the assembly clip no longer serves a function.

    Abstract: A valve control system (15) in which there is provided a deactivating rocker arm (51) disposed beneath a conventional, upper rocker arm (27), and disposed within a module housing (17). The deactivating rocker arm includes a latch tab (63) and when the latch tab engages (FIG. 3) a latch member (65), the system operates in a normal, valve activating mode. When the latch member is in an unlatched condition (FIG. 4), the deactivating rocker arm pivots, compressing the valve return spring (41), which thereafter serves as the required lost motion spring, biasing the deactivating rocker arm (51) and lash compensation device (35) back toward their normal position.
