Abstract
A hydraulic system for actuating a belt-driven conical-pulley transmission having a variably adjustable transmission ratio, of a vehicle, including at least one hydraulic energy source and having a torque sensor that is supplied with working medium by a pump flow of the hydraulic energy source. A disconnection valve is connected between the hydraulic energy source and the torque sensor, which makes it possible to connect or disconnect an additional pump flow of the hydraulic energy source, depending on need.
