ABSTRACT:
A radio frequency gasket assembly having a flexible hollow tube enveloped a conductive layer, and filled with a compressible fluid, or a combination of both compressible and incompressible fluids. In one embodiment thereof, the undeformed gasket is filled completely with a compressible fluid, such as air. When the gasket is compressed, a portion of the fluid is allowed to collect in a spring-loaded reservoir, maintaining at all times a substantially constant internal pressure. When the compressive force is removed, the collected fluid re-enters the gasket, which may then assume its original undeformed profile. In another embodiment thereof, the undeformed gasket is filled with a mixture of both compressible and incompressible fluids. When the gasket is compressed, a portion of the compressible fluid is evacuated or collected in a spring-loaded reservoir or the like, maintaining at all times a substantially constant internal pressure. When the compressive force is removed, an equal amount of compressible fluid is re-introduced into the gasket, which may then assume its original undeformed profile.
