Abstract
In a fly-wheel unit of any desired construction type including two separate fly-wheel members, the torsion springs are housed in a liquid receiving chamber which is at least partially filled with a lubricant or with a coolant. In this way inherent noises and excess wear can be damped and heat generation can be uniformly distributed.
