DEVICE FOR VARIABLY ACTUATING THE GAS EXCHANGE VALVES IN RECIPROCATING ENGINES

摘要

The aim of the invention is to fulfill, better than the prior art, the deman ds placed by the engine on a variable valve control with regard to the shaping and accuracy of the valve lifting curves with regard to the simplicity of th e structural design of the valve drive and of the associated adjusting mechani sm and with regard to mechanical losses due to friction. These demands are fulfilled without any additional structural complexity, particularly pertaining to the overall height. This is achieved by the provision of a rotatable drive consisting of a housing (G), a shaft (W), an intermediate element (Z) and of an output element (A).
