Abstract

The present invention relates to a vibration control or vehicular suspension system. In one embodiment, the system uses a liquid spring (200) filled with a compressible liquid. In such an embodiment, a suspension system, in addition to being able to change stiffness and damping properties, has the ability to level a vehicle or other structure or device to a desired height and compensate the level height for the addition or subtraction of load.
