To provide for rapid response of a fluid pressure element pressing conical disks towards each other, to prevent slippage of a belt (25) between the conical faces of the conical disks (3, 3', 4, 4') upon abrupt changes in torque being transmitted to the driving shaft (1; 51, 52); additional fluid supply lines (23, 24; 73, 74) with check valves therein (21, 22; 71, 72) are connected between the torque sensor (19; 69, 70) and the connecting line (11, 12; 61, 62) extending between a control valve (10; 50) and the fluid pressure arrangement, typically a cylinder-piston arrangement (5, 7, 8, 6, 9), providing axial pressure of the movable one of the conical disks, the check valves having a fluid path direction from the pressure source-torque sensor line (18; 65, 75, 218) to the control valve (10, 50)-fluid pressure arrangement line (11, 12; 61, 62) and bypassing the control valve (10; 50). |
