    摘要： A system for selectively deactivating engine valves of a cylinder of an internal combustion engine. The system employs switching rocker assemblies between the valves of the engine and rotating cam lobes. The disclosed design is able to operate using a single cam lobe per valve. The rocker assembly employs a first arm pivotally attached to a second arm at one end. The first arm engages the valve and the second arm has a roller bearing that engages the cam lobe. A latch causes the first and second arm to move in unison following the cam surface when latched. When unlatched, the second arm follows and moves according to the rotating cam surface, but the first arm does not follow and does not actuate the valve, thereby deactivating the cylinder.

    摘要： A lubrication structure for a rocker arm includes a lash adjuster mounted in an accommodating portion located in an end of the rocker arm and a pushrod abutting against a lower end of the lash adjuster. The rocker arm is formed with an arm-inside oil supply passage for supplying lubrication oil to the lash adjuster. The lubrication oil guided into the accommodating portion is further guided through a through guide hole of the accommodating portion to an outer peripheral surface of the accommodating portion. The lubrication oil is further guided from an outer oil supply passage formed downwardly in the outer surface of the accommodating portion to the abutment between the lash adjuster and the pushrod.

    摘要： A deactivating rocker arm for use with a cam having at least one no-lift safety lobe is provided. Safety lobe contacting surfaces on the rocker arm are configured for contact with safety lobes during abnormal operation of the rocker arm. When the rocker arm is deactivated, the safety lobe contacting surfaces may come into contact with safety lobes when excessive pump-up of a lash adjuster brings the rocker arm undesirably close to the rotating cam. This contact limits the range of motion of the rocker arm during certain instances of abnormal operation, promoting more effective transition between deactivated and activated states and preventing damaging contact between the rocker arm and the cam lobe.
