Abstract
A combined environmental and electromagnetic rotary seal. The invention is adapted for use between two mutually rotating components of an electromagnetic energy transmission system and provides simultaneous protection against contamination from the environment and unwanted electromagnetic leakage. In the illustrative embodiment, a first set of grooves is cut into the exterior of a first conductive cylindrical component whose interior contains a portion of a millimeter-wave beam waveguide energy transmission system, the grooves comprising the electromagnetic portion of the seal and a second set of grooves is cut into the interior of the conductive housing enclosing the first conductive cylindrical component. The second set of grooves comprises the environmental portion of the seal when a set of standard environmental seals (such as elastomeric o-ring seals) are seated in each groove in the second set of grooves and each seal is compressed between the groove in which it is seated and the exterior of the first conductive cylindrical component. The environmental seals maintain a nearly uniform annular gap between the first conductive cylindrical component and the conductive housing such that the two conductors do not make physical contact.
