Hydraulic system for providing pressures and volumetric flows in a dual clutch transmission

A hydraulic system for providing pressures and volumetric flows in a dual clutch transmission, comprising:

• a first clutch
• a second clutch
• a first feed line providing a volumetric cooling flow for said first and second clutches;
• a second feed line providing a volumetric lubricating flow for said first and second clutches;
• at least one switching valve upstream of said first and second clutches, the switching valve having:
• a first inlet port connected to the first feed line,
• a second inlet port connected to the second feed line,
• a first outlet port connected to the first clutch, and
• a second outlet port connected to the second clutch;
• wherein
• said first and second feed lines are separated from each other;
• said switching valve is controlled for guiding in a controlled manner in a first position the lubricating flow onto the first clutch and the cooling flow onto the second clutch and in a second position the lubricating flow onto the second clutch and the cooling flow onto the first clutch.
