ABSTRACT:
A cylinder head assembly of an internal combustion engine includes valves arranged in the cylinder head. For the purpose of driving each of the valves, a respective push rod is provided which is driven by a cam shaft and carries a rocker which is mounted on a rocker shaft. The rocker shaft is held in individual rocker brackets in such a way as to accommodate pivotable movement of the rockers about the said shaft. In order to obtain a rocker bracket which is easy to preproduce and requires virtually no further machining for installation, each rocker bracket has, at its upper end, a trough-shaped depression for the purpose of accommodating the rocker shaft.
