DYNAMIC DAMPENER Russian patent published in 2009 - IPC F16F6/00 F16F9/53 F16F9/504 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to mechanical engineering, particularly to dampeners of vibrations of mechanical engineering equipment. The dynamic dampener of vibrations consists of a case, divided into three chambers by means of elastic elements in form of membranes and an insertion. The upper and lower chambers are filled with magnetic liquid, while the middle one is filled with air. Systems of channels arranged in the insertion connect the upper and lower chambers. The case of the dampener is enveloped with a coil connected to a control block. From the sensor of vibration acceleration installed on the projecting rod of the insertion signals are transmitted to the control block.

EFFECT: expanding working range of frequency damping and its regulating.
