ABSTRACT:
A damper-type flywheel comprises two coaxial parts adapted to rotate relative to each other about their common axis. A circumferentially acting spring device is operatively disposed between the two coaxial parts. An annular fluid-tight cavity is defined between the two coaxial parts. A viscous damper device accommodated in the fluid-tight cavity is mechanically disposed between the two coaxial parts. The viscous damper device may comprise two groups of fins in the annular cavity each constrained to rotate with a respective one of the two coaxial parts, the annular cavity containing a viscous, preferably non-Newtonian fluid such as a silicone-based fluid.
