ABSTRACT:
Vibration equipment bases which are isolated from the floor by air bags are made self-leveling by interposing a valve between each of the air bags and a pressurized air supply and each of the air bags and the atmosphere, the valve being sensitive to height of the base in air flow controlling relation to and from the bags to adjust their inflation and thus the height of the base.
