ABSTRACT:
A control valve arrangement for a continually variable transmission includes a first valve for regulating pressure in a primary servo for the gear ratio of the transmission and a second valve for regulating pressure in a secondary servo controlling tension of the drivebelt. These valves are acted upon by a throttle shaft as a function of output torque of the engine. A modulating device varies pressure in the secondary servo as a function of the gear ratio and of engine torque. The modulating device comprises a lever having one end acted upon by a cam disk as a function of the engine torque and second end acted upon by a valve element of the second regulating valve. The second lever is extended radially outward from a pivot. A sensor arm acts as a function of the gear ratio on one end of the second lever, whose other end is rotatably pinned to the first lever.
