Rotational vibration damper for internal combustion engine, has secondary masses arranged over viscous liquid in chamber, and spacer arranged between two oppositely arranged masses, where spacer is torque proofly connected with housing

摘要

The damper has a set of secondary masses (4a, 4b) arranged in a housing, where the masses are arranged over a viscous liquid in a chamber that is in contact with the housing. A spacer (11) is arranged between two oppositely arranged masses, where the spacer is torque proofly connected with the housing. The masses and the spacer are arranged in such a manner that the masses are not affected during an operation of the dampers.
