Abstract
An oil supply system for the overhead valve actuating mechanism of an internal combustion engine. A cam follower is engaged by a hydraulic tappet for constantly maintaining positive contact among the valve actuating mechanism components including a rocker arm pivotally mounted on a rocker shaft and engaging the end of the valve for opening same and a pusher rod extending between the rocker arm and the cam follower. Oil is supplied under pressure to the hydraulic tappet for operating same and from a reservoir chamber in the tappet through oil passages in the cam follower, pusher rod and rocker arm to lubricate the rocker shaft and the points of engagement between those components.
