Abstract
In a continuously variable transmission with a toroidal variable speed drive, in which a roller is supported pivotably between two toroidal disks for transmitting motion between the two toroidal disks at transmission ratios which depend on the pivot position of the roller according to pressure forces acting on a hydraulic actuating piston, for the purpose of varying the transmission ratio, two regulating slide valves are provided, each including a regulating slide with control edges to act upon the hydraulic actuating piston via a hydraulic medium under the control of the regulating slide valves each controlling the pressure in one of the chambers arranged at opposite ends of the actuating piston.
