Hydrodynamic coupling device

摘要

A shock-absorbing device (96) for a torsional vibration absorber (80) has a sealed structure (100) to cover an energy-storing components (130,132) expansion area for causing separation in a first flow path (FP) for a fluid substance (FS) between a first flow way (FW) (146) and a friction area (69) and separation in a second FP for an FS between a second FW (154) and a hydrodynamic circuit (24).
