ABSTRACT
A pneumatic anti-vibration mounting with a flat or inverted dish
type top cover for mounting equipment below which is an inflatable
hollow chamber in the approximate form of a toroid. A central
threaded bush attached below the top cover and passing down through
the centre of the hollow chamber passed into a cavity in the base
which is attached to the bottom of the hollow chamber. Secured to
the bottom of the central bush is a sit down bump stop. A captive
version of the mounting has an extended base plate with fixing down
holes. Inflation of the chamber via a valve or connection in the
base or air chamber wall, causes the mounted equipment to rise
thereby forming a very efficient vibration and shock isolator.
