Abstract

A rocker arm for an internal combustion engine having overhead camshaft. The rocker arm includes an internal lubrication passage connecting the fulcrum socket and the cam pad. During engine operation oil is provided under pressure to the rocker arm from the fulcrum member and is discharged at the cam pad directly beneath the cam surface. The passage may include an oil reservoir beneath the cam pad which retains a predetermined quantity of oil when the engine is not in operation and which provides essentially instantaneous lubrication to the cam pad and cam surface upon start-up of the engine.
