ABSTRACT:
Disclosed is a torsional vibration damper arrangement, especially for the drive train of a vehicle, including a primary side and a secondary side which is coupled to the primary side by a damper fluid arrangement in order for the primary side and the secondary side to rotate about an axis of rotation and rotate relative to one another. The damper fluid arrangement encompasses a first damper fluid that has low compressibility and transmits torque between the primary side and the secondary side as well as a second damper fluid which is more compressible and is loaded when the pressure of the first fluid increases.; The torsional vibration damper arrangement is characterized in that a volume containing the second damper fluid is disposed outside the primary side and outside the secondary side and does not rotate about the axis of rotation along with the primary side and the secondary side.
