Abstract
A lubricating system of an internal combustion engine is equipped with intake and exhaust valves and a valve operating mechanism having rotating portions and reciprocating portions. The rotating portions are communicated with an oil pump via a first oil path and the reciprocating portions are also communicated with the oil pump via a second oil path. The rotating portions have a cam shaft in operative connection with a crank shaft. The reciprocating portions include a rocker follower pivoted to a follower shaft and engaging the cam shaft, a rocker arm pivoted to a rocker shaft and operatively connected to the intake or exhaust valve, and a push rod connecting the rocker follower and rocker arm. A series feed oil path is defined in the follower shaft, rocker follower, push rod, rocker arm and rocker shaft so as to pass through their mutual contact portions, and is communicated with the oil pump via the second oil path. Accordingly, in this construction the mutual contact portions between the rotating portions and the reciprocating portions can effectively be lubricated by one lubricating system.
