Patent ID: 7416069

Claim:
A clutch arrangement in an automatic transmission, the clutch arrangement comprising axially adjacent multi-disc radially outer and inner clutches (B, E) each of which having a piston-cylinder arrangement for axial clutch actuation, a pressure space for axial actuation, a pressure compensation chamber ( 25 ) for a dynamic clutch actuation pressure compensation and a lubricant system for lubricant or coolant supply, the radially outer and the radially inner clutches (B, E) being disposed radially one above another, the piston-cylinder arrangement for actuation of the radially outer and the radially inner clutches (B, E) are at least, to a great extent, axially disposed side by side, the pressure compensation chamber ( 25 ) for the radially outer clutch (B) is located axially next to the pressure space ( 8 ) for actuation of a piston ( 17 ) of the radially inner clutch (E) and a lubricant or coolant ( 30 ) for the radially outer clutch (B) is tapped from the pressure compensation chamber ( 25 ) for actuation of the radially outer clutch (B).
