Abstract

The support is so arranged as to have a wider damping characteristic. For this purpose, it comprises two expansion chambers connected to the same work chamber by ducts having different characteristics so that the liquid contained in these ducts is put into resonance at different frequencies. The two expansion chambers are disposed concentrically to each other on the same side of the work chamber and are defined by a separating partition and by a single diaphragm.
