Abstract
A lubrication system for the valve actuating mechanism of an internal combustion engine having a vertical drive shaft and horizontally oriented cylinder includes a rocker box housing the valve actuating mechanism with the valve actuating mechanism including a lower rocker arm and an upper rocker arm each oriented for rocking in a substantially horizontal rocking plane. A push rod cavity communicates at one end with the crankcase and at the other end with the rocker box. A cam shaft gear disposed at a lower end of a vertical cam shaft slings liquid oil from the crankcase through the push rod cavity into the rocker box. A dam is provided for retaining liquid oil in the rocker box at a level which partially submerges the lower rocker arm such that the rocking motion of the lower rocker arm splashes dammed oil to lubricate the valve actuating mechanism.
