In a control valve arrangement for a continuously controllable belt drive, which has a first control valve for the pressure in the primary servo for the translation of the belt drive and a second control valve for the pressure in the secondary servo for the tension of the belt drive, and these two control valves are acted on by the throttle flap shaft, as a function of the speed and of the torque of the drive motor, and a modulation device varies the pressure in the secondary servo as a function of the translation and the torque from the engine, the modulation device consists of a lever arrangement (12 and 15), a cam disc (7) acting on the first lever (12) on one end (13), as a function of the torque, and the other end (14) of the first lever (12) acting on the valve element (9) of the second control valve (8), and the second lever (15) being rotatably supported between its ends via a bolt (16) and a sensor rod (11) acting on its one end (18) independently from the translation and which second lever (15) is connected, such that it can rotate, by its other end (19) via a pin (20) to the first lever (12). …<IMAGE>… |
