Abstract: A controllable hydraulic vibration-damping support comprising two strength members interconnected by an elastomer body defining a working hydraulic chamber, an auxiliary hydraulic chamber communicating with the working chamber via a constricted passageway, a pneumatic chamber separated from the auxiliary chamber by a moving wall, an electrically controlled vent device for establishing a connection to the air, which device can be actuated electrically in order to put the pneumatic chamber into communication with the atmosphere, and a check valve allowing air to flow only out from the pneumatic chamber towards the atmosphere.

Abstract: Active hydraulic anti-vibration mount comprising two support elements connected by an elastomer body partially delimiting a working chamber filled with liquid, this working chamber communicating by a throttled passage with a compensation chamber separated from said working chamber by a rigid partition. The rigid partition is penetrated by a first regulating nozzle closed by a movable exciting device, and a second regulating nozzle closed by a valve the movements of which are limited to correspond to an amplitude of variation in the volume of the working chamber which is less than 20% of the amplitude of the variations in volume generated by the exciting device.

Abstract: An anti-vibration support comprising two rigid frames joined to one another by an elastomer body which is applied against a rigid partition to define a hydraulic working chamber linked to a compensating chamber by a throttled passage. The liquid contained in the working chamber is in contact with a piston controlled by an electromagnetic actuator with a proportional electromagnet.

Abstract: Electromagnetic actuator including a mobile magnetic member made up of stacked ferromagnetic plates and two fixed electromagnets for reciprocating the mobile magnetic member along a central axis. The ferromagnetic plates each have two opposite edges parallel to the central axis which are crimped to two rigid transverse strips. Elastomer bodies join each transverse strip to a fixed spacer.

Abstract: An anti-vibration support is provided having two rigid frames linked to one another by an elastomer body which is applied against a rigid partition to delimit a hydraulic working chamber connected to a compensating chamber by a throttled passage. The rigid partition has a flexible membrane inserted between the working chamber and a pneumatic chamber controlled by a solenoid. The solenoid is mounted on a support block which also incorporates a pneumatic coupling and an electrical connector, this support block having an annular flange which delimits the pneumatic chamber and clamps the flexible membrane against the rigid partition.

Abstract: The hydraulic antivibration support has two rigid strength members interconnected by a bell-shaped elastomer body, a flexible elastomer wall connected to the second strength member, and a rigid partition secured to the second strength member and defining both a working chamber on its elastomer body side and a compensation chamber on its flexible wall side. These two chambers are filled with liquid and are connected to each other via a narrow channel, via a central nozzle fitted with an axially movable shutter, and via an annular flap disposed around the central nozzle between two grids. One of the grids is axially slidable and is connected to the shutter so as to block the flap when the shutter is open.
