Abstract
A transmission has an rpm-converter controlled by a hydraulic system. The hydraulic system has a supply circuit from a fluid-conveyor device to the rpm-converter, a return circuit to carry the spent fluid back from the rpm-converter, and a run-off circuit to return the run-off portion of fluid from a flow-regulating device that regulates the volume flow in the supply circuit. The return circuit and the run-off circuit are merged in a circuit junction that continues into a flow-back circuit.
