Motor vehicle internal combustion engine valve rocker has outer arm with relatively pivotable inner arm to adjust valve timing

摘要

The motor vehicle internal combustion engine rocker has an outer arm (2) formed by a pair of levers (3) and an inner arm (4) between these, which is relatively pivotable to them. The free ends of the outer arms form an abutment (8) for the end of the valve stem. The inner arm is pivoted on an axis (24) offset from the outer arm axis and carrying a cam follower (11,12).
