Hydraulic antivibration supports

摘要

The invention relates to a hydraulic antivibration support designed to be interposed between two rigid elements. It comprises a working chamber and a compensating chamber separated by a rigid partition and connected permanently with one another through a throttled passage. Both of these chambers and this passage are filled with liquid. The working chamber is composed of two compartments connected to one another through a throttled annular column bounded internally and externally by two cylindrical surfaces fast respectively to the two rigid elements.
