Abstract
A hydraulic anti-vibration support includes a rigid frame 3, a head 1, a frustoconical elastomer wall 6 connecting the cylinder to the head, a membrane 7 carried by the cylinder, a partition 8 separating the inside of the resulting liquid-filled enclosure into a working chamber A and a compensating chamber B, a throttled passage 9 interconnecting the two chambers, a small displacement piston 12, and an electrical exciter 14 suitable for setting up counter-vibrations in the piston. An air-filled capsule 19 defined by the piston and by a rigid wall 20 secured to the frame by a slotted spacer 21 is immersed in the working chamber, the piston being disposed between the wall and the exciter, and the periphery of the piston being connected to the wall by a sealed and deformable annular gasket 23.
