ABSTRACT:
Sealing apparatus seals the opening of a chamber by seating a double lip seal--or a functionally equivalent seal--between the chamber and the door of the chamber when there is an insufficient pressure differential across the seal to seat it properly. The apparatus includes a vacuum pump which evacuates air from the enclosed space defined by the chamber, the chamber door, and the two flexible members of the sealing device to force the sealing device against the chamber and the chamber door. A storage tank can be provided which can be evacuated of fluid to reduce the capacity of the vacuum pump, or to eliminate it altogether when the sealing apparatus is used with a chamber equipped with a vacuum pump.
