Abstract

The invention relates to a hydraulic circuit having a first hydraulically actuable clutch that is closed in a rest state and a second hydraulically actuable clutch that is closed in the rest state, wherein the hydraulic circuit is configured in such a way that a hydraulic medium present in a main pressure line can be loaded with a working pressure by a pressure generating device and/or a pressure accumulator, and the hydraulic medium can be discharged for pressure dissipation via a main return line into the return reservoir. In some embodiments, the hydraulic circuit has a first distributor pressure line and a separate, first collector return line for the hydraulic supply of a first part circuit and at least one separate, second distributor pressure line and at least one separate, second collector return line for the hydraulic supply of a second part circuit, and the first clutch is assigned to the first part circuit and the second clutch is assigned to the second part circuit.
