HYDRODYNAMIC COUPLER

Disclosed is a hydrodynamic coupler, in particular a torque converter, in which the torsion damper arrangement (34) comprises a first torsion vibration damper area (64) with a first inlet area (68) connected to the second friction surface formation (46) and a first outlet area (72) coupled to the first inlet area (68) via a plurality of first damper spring units (76), and a second torsion vibration damper area (66) with a second inlet area (78) connected to the first outlet area (72) and a second outlet area (82) coupled to the second inlet area (78) via a plurality of second damper spring units (84). The first outlet area (72) is connected to the second inlet area (78) via a third torsion vibration damper area (94), and a subassembly of the first inlet area (68) and the first outlet area (72) forms a closing surface (86) enclosing the first damper spring units (76) radially outward at least in certain areas. At least one first damper spring unit (76) is guided at least partially in a friction-disconnected or friction-reducing manner with respect to the closing surface (86).
