Abstract
Active hydraulic anti-vibration support comprising two armatures joined by an elastomer body partially bounding a working chamber filled with liquid and communicating with a compensating chamber, an exciter member in contact with the working chamber, a control device designed to displace the exciter member and an elastic return device applying a force to the exciter member to return it to its non-operating position in accordance with a certain elasticity curve which has a tangent for a first displacement value corresponding to the non-operating position of the exciter member. The elasticity curve is located below this tangent in the vicinity of a second displacement value corresponding to the end stop position of the exciter member.
