ABSTRACT:
Infinitely variable transmission for a device with an internal combustion engine (67) is provided with an endless transmission member (14) which has been looped over two pulleys, each having a running groove situated between conical pulley halves (2,3 and 8,9 resp.), at least one conical half of each pulley being axially movable through an associated hydraulic cylinder (4,12), also provided with a first control valve (40) for regulation of the fluid pressure in the cylinder (12) of the driven pulley and in the supply line to a second control valve (20), which second valve is intended for the adjustment of the transmission ratio by regulation of the amount of fluid supplied to and discharged from the cylinder (4) of the driving pulley. Devices have been provided for the operation of the first control valve (40) which bring about an increase or a decrease of the fluid pressure in the cylinder (12) of the driven pulley, depending on the movements of the engine block.
