Torsional Vibration Dampers (TVD)
CORA TVD's stand high loads as our premium
quality rubber compounds maximize their damping properties.

Decoupled Dampers or DDS (Double Damping System Dampers)
Decouplers are made up of a TVD assembled with a torsional coupling, so-called
â??isolatorâ??. DDS special design helps to eliminate crankshaft vibrations at low
the frequency through the crankshaft isolator rubber while the TVD reduces the
torsional vibrations at high frequency inside the crankshaft.

Viscous Dampers
In VISCOUS dampers, the viscous oil layer placed between the inertia ring and pulley
body runs the energy dissipation and converts it into heat. This technology can
dampen a wide range of crankshaft natural frequencies from different orders.
We hold two patents on innovative construction solutions for viscous dampers.
