Abstract: A cone pulley transmission is disclosed which includes an infinitely actuatable and adjustable transmission wherein an axially displaceable cone pulley disc is adjustable by application of hydraulic tensioning so as to generate the pressure forces acting on a transmission belt rotating between the cone pulley discs, with the tensioning being controlled by a pressure medium through a sliding control valve. The tensioning is provided by different sized pressure chargeable surfaces and is throttled to different degrees with respect to the associated outlet of the sliding control valve. In this connection, it is provided that at least one outlet can be changed as a function of certain parameters.
