Patent ·
OSTI ID:6619134
;
This patent describes an oil supply system for a valve actuating mechanism of an internal combustion engine wherein the valve actuating mechanism includes a rocker arm pivotally mounted on a rocker shaft and engaging a head of a valve, a hydraulic tappet, and a cam follower and interlinking mechanism interconnecting the hydraulic tappet to the rocker arm for actuating the valve. The improvement described here comprises an oil supply passage communicating with an oil reservoir chamber in the hydraulic tappet, and oil passage means in the rocker arm and cam follower and interlinking mechanism in mutual communication and communicating with the hydraulic tappet oil reservoir chamber and rocker shaft for supplying lubricating oil from the reservoir chamber to the rocker shaft.
