Abstract:
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.
