摘要

The rotor vibration absorber has a drive shaft (10) and rigid section (6) absorbing vibrations and hydraulic deadening (3) in a cavity. There is a compensation cavity communicating with the viscous fluid deadening cavity. There is a flexible membrane (70) in the fluid deadening cavity and filled with gas. The membrane is a set distance from the internal wall (26).
