Antivibration device comprising two frames and an elastomer body interconnecting said frames and delimiting a first hydraulic chamber linked to a second deformable hydraulic chamber via a throttle passage. A microturbine is rotatably mounted in the throttle passage and is coupled to a generator. The microturbine is configured to be always driven in the same rotational direction by the fluid when the fluid reciprocates along opposing first and second paths within the throttle passage.

Hydraulic anti-vibration device provided with an electricity generator device and electricity generator device for such an anti-vibration device

Vibration damping device comprising two armatures and an elastomer body that connects armatures together and which delimits a first hydraulic chamber that communicates with a second hydraulic chamber that can be deformed by a constricted passage. A sealed box, integral with the second armature, contains a control device and an actuator. The box is sealed and comprises at least one flexible wall separating from the atmosphere, the interior space of the box.

Hydraulic antivibrating device

Vibration damping device comprising two frames and an elastomer body that connects frames together and which delimits a first hydraulic chamber that communicates with a second hydraulic chamber that can be deformed by a constricted passage. An electromagnetic actuator, that controls the vibration damping behavior of the device, comprises a a permanent magnet holding machanism.

Controllable hydraulic vibration-damping support comprising a rigid block, a bell-shaped elastomer body becoming wider from the block to an annular strength member, a working chamber, a compensation chamber, a constricted passageway connecting the working chamber to the compensation chamber, and an auxiliary chamber separated from the working chamber by a decoupling valve controlled by a control device. The auxiliary chamber, the decoupling valve and the control device are in the block.

Controllable hydraulic vibration-damping supports

Controllable hydraulic vibration-damping support comprising a main hydraulic circuit comprising a working chamber, a compensation chamber, and a first constricted passageway, and an auxiliary hydraulic chamber separated from the working chamber by a decoupling valve and communicating with the main hydraulic circuit by means of a second constricted passageway having a resonance frequency of less than 5 Hz. The auxiliary chamber is separated from a pneumatic chamber by a movable wall, and a control device is provided for selectively either connecting the pneumatic chamber to the open air, or bleeding air from the pneumatic chamber.

Hydraulic vibration-damping support

A hydraulic anti-vibration mount having two damping modes, is disclosed comprising two support members, an elastomer body that connects the two support members to each other, a working chamber, a first structural plate with a check valve, a calibrated hole, a first restricted passage linking the working chamber to an intermediate chamber, a second structural plate having a main port, a second restricted passage, linking the intermediate chamber to a compensation chamber, an auxiliary chamber supplied by the check valve and emptied by the calibrated hole, and equipped with a flexible membrane arranged for deforming and closing the main port, to switch between the two damping modes.
