1. A hydraulic system comprising:
a first pump, which provides fluid at a first volumetric flow and a first pressure for a cooling and/or lubricating device at a first outlet;
a second pump, which provides fluid at a second volumetric flow and a second pressure for at least one first hydraulic load at a second outlet, the first volumetric flow being greater than the second volumetric flow, the second pressure being higher than the first pressure;
a system pressure valve; and
an additional active valve connected upstream of the cooling and/or lubricating device, the additional active valve being connected to the system pressure valve and to at least one second hydraulic load to be boosted in such a manner that in a boost state, the first and second outlets being connected to the at least one second hydraulic load via a boost line.

13. A hydraulic system comprising:
a first pump configured for providing fluid at a first volumetric flow and a first pressure at a first outlet to a cooling and/or lubricating device;
a second pump configured for providing fluid at a second volumetric flow and a second pressure at a second outlet to at least one first hydraulic load, the first volumetric flow being greater than the second volumetric flow, the second pressure being higher than the first pressure;
a system pressure valve connected between the first outlet and the second outlet; and
an additional active valve connected upstream of the cooling and/or lubricating device, the additional active valve being connected between the system pressure valve and at least one second hydraulic load for being boosted in such a manner that in a boost state, the additional active valve is configured for connecting the first and second outlets to the second hydraulic load.
