    Abstract: An isolation system including three discrete pneumatically controlled, self-positioning, shock and vibration isolators, each isolator including a chamber for air under pressure which acts as the isolator or load supporting chamber and provides an outlet to ambient, controlled by a position control valve. One wall of this chamber is formed with a tapered inlet opening to provide a valve seat for accommodating a ball inlet valve attached to a plunger of a height control valve. The other end of the plunger contains another ball serving as an air outlet valve, that is adapted to be seated in a tapered opening in the isolated body mounting. When the isolated body mounting moves inwardly into the chamber it presses on the upper ball to produce a force transmitted by the height control valve plunger upon the lower ball that opens the inlet valve to cause an increase of pressure in the chamber which serves to raise the isolated body mounting platform. When the platform rises, the outlet valve is opened by withdrawal of the outlet valve seat to reduce the pressure, and, in turn, causes the platform to again be urged inwardly into the chamber. According to another aspect of the invention, there is a bias chamber for providing a downward force against the support piston and providing supply air to the height control valve, the pressure in the bias chamber being greater than the pressure in the load carrying chamber.
