Abstract
A hydraulic system is provided for supplying at least one hydraulic consumer with at least one supply pump, a consumer connection, a return connection, a cooling circuit and a tank. The at least one cooling circuit comprises a cooling pump, a circulation cooling line connected to the tank and a heat exchanger. The cooling pump and the heat exchanger are disposed in the circulation cooling line. Downstream of the cooling pump and upstream of the heat exchanger, a branch line connected to the consumer connection branches off from the circulation cooling line and the cooling circuit comprises a switching valve. The switching valve can be switched between a closed position and an open position, wherein the circulation cooling line is closed in the closed position, so that the cooling pump is only connected to the branch line. In the open position, the cooling pump is connected to the heat exchanger.
