Rotation speed-adaptive torsional vibration damper arrangement for rotatable powertrain of motor car, has flow control device comprising centrifugal force-regulated flow controller to control exchange of fluid during rotation of arrangement

摘要

The arrangement (10) has a primary side (11) relative to which a secondary side (12) is rotatable against effect of a damper fluid arrangement (13) around a rotational axis (14). The fluid arrangement has a first fluid chamber (15a) and a second fluid chamber to receive damping fluid. Each chamber has boundaries respectively connected with the primary and secondary sides so that volume of the chamber is changeable by relative movement of the sides. A flow control device (20) has a centrifugal force-regulated flow controller to control exchange of the fluid during rotation of the arrangement.
