  • Valve drives with intermediate links are known in many different designs become, the intermediate member a rocker arm mounted at one end or a can be two-armed rocker arm.
  • Valves offer valve trains with such transmission elements significantly improved Possibilities of adaptation to the structural conditions and desired Properties of the internal combustion engine, especially with regard to a variable Valve control, i.e. So an adjustability of the opening or closing time as well the opening period.
  • a valve train is, for example, FIGS. 29 and 30 WO 98/26161 A, according to which an end bearing for the intermediate member an eccentric is arranged and can be adjusted by turning the eccentric. The The two bearing axes are therefore close to each other, with the distance of the eccentricity equivalent.
