Abstract
In order to eliminate components in an internal combustion engine, and to thereby reduce the cost and weight while enhancing compactness in a rigid yet quiet arrangement, a valve train assembly is disclosed. The internal combustion engine has a valve with an integral valve stem, a valve lifter in engagement with a cam, and a rocker arm in engagement with the valve stem. The valve train assembly is such that the rocker arm is in engagement with the valve lifter at a first point along its length and is in engagement with the valve stem at a second point along its length. The rocker arm has a recess at the first point along its length for receiving and engaging the valve lifter therein. The valve train assembly is also such that the rocker arm has a surface at the second point along its length to thereby move the valve in response to movement of the valve lifter. The internal combustion engine also includes a mounting for the rocker arm at a point intermediate the first and second points along its length for pivotal movement thereof. With these features, the valve train assembly is such that movement of the valve lifter is imparted through the rocker arm to the valve stem in a most hi…
