Beschreibung
Zusammenfassung:	The invention provides an overhead rocker arm valve bridge air distribution driving mechanism which comprises a cam shaft, a rocker arm structure, a valve bridge structure and two air valves, the rocker arm structure is installed in an engine through a rocker arm shaft, the top of the rocker arm structure makes contact with the outer wall of the cam shaft, and the cam shaft is installed in the engine. One side of the rocker arm structure makes contact with the upper surface of the valve bridge structure, the two sides of the valve bridge structure are connected with the two valves respectively, and each valve is installed in an engine through a valve spring seat and a valve spring. According to the overhead rocker arm air distribution driving mechanism with the valve bridge, the valve bridge is additionally arranged between the rocker arm and the valve, so that valve lateral force caused by lateral sliding between the rocker arm and the valve is eliminated, and abrasion between the valve and a guide pipe in a
