Patent ID: 7740119

Claim:
A dual clutch transmission, comprising: a first volume flow valve for activating a first clutch, the first clutch being located downstream of the first volume flow valve; a second volume flow valve for activating a second clutch, the second clutch being located downstream of the second volume flow valve; a first hydraulic energy source for supplying the first volume flow valve and the second volume flow valve and the first clutch and the second clutch with a system pressure; and a fluid cooling unit in fluid communication with the first clutch and the second clutch, the fluid cooling unit located downstream of the first volume flow valve, wherein, the first volume flow valve has a first switching position and a second switching position, in the second switching position, the first hydraulic energy source is connected to the fluid cooling unit, for cooling the first clutch and the second clutch, the fluid cooling unit being capable of being supplied with a comparatively low cooling pressure by means of the first hydraulic energy source.
