Detachable coupling for pressure-medium-filled HF lines

DETAILED DESCRIPTION The problem is solved by providing valves in both of two joined line sections.
The valves are designed to open automatically when the lines are connected and to close automatically when the lines are separated.
When they are open, the valves connect the gas-filled portions of the two line sections.
The high-frequency line thus itself serves as air supply line and the valves may be accommodated in the high-frequency chamber or within the inner conductor of coaxial lines.
When a coupling is separated, for example a plug connection in the case of coaxial conductors, the air or gas passage through the line is automatically closed, by checkvalves or spring-actuated valves, so that the desired sealing or connection is obtained automatically without additional actuation.
Further expedient developments of the invention in coaxial line couplings or hollow waveguide couplings are apparent from the subsidiary claims.
