Abstract
Abstract A coupling for the gas-tight connection of two spacedly arranged substantially tubular-shaped casing sections equipped with outer end flanges of gas-blast insulated switching installations, comprising a coupling sleeve consisting of semi-circular cups or half shell elements secured by means of their outer end flanges at the end flanges of the casing sections. Within the coupling sleeve there is provided a substantially tubular-shaped jacket seal equipped with two ring-shaped flange seals formed at its ends and within such jacket seal a support sleeve consisting of semi-circular cups or half shells. Each flange seal of the jacket seal engages between an end flange of the coupling sleeve and the end flange of the associated casing section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A coupling arrangement for the gas-tight connection of two spacedly arranged substantially tubular-shaped casing sections of gas-blast insulated switching installations, the casing sections being provided with outer end flanges, comprising a coupling sleeve having outer end flanges and composed of substantially half shells, said coupling sleeve being secured by means of its outer end flanges to the end flanges of the casing sections, a substantially tubular-shaped jacket seal arranged within the coupling sleeve, said jacket seal having two substantially ringshaped flange seals formed at its two ends, a support sleeve arranged within the jacket sleeve, said support sleeve comprising half shells, and wherein each flange seal of the jacket seal engages between an end flange of the coupling sleeve and the end flange of the one associated casing section.
Claim 2
Dependent Claim
129 words
A coupling arrangement for the gas-tight connection of two spacedly arranged substantially tubular-shaped casing sections of gas-blast insulated switching installations, the casing sections being provided with outer end flanges, comprising a coupling sleeve having outer end flanges and composed of substantially half shells, said coupling sleeve being secured by means of its outer end flanges to the end flanges of the casing sections, a substantially tubular-shaped jacket seal arranged within the coupling sleeve, said jacket seal having two substantially ringshaped flange seals formed at its two ends, a support sleeve arranged within the jacket sleeve, said support sleeve comprising half shells, and wherein each flange seal of the jacket seal engages between an end flange of the coupling sleeve and the end flange of the one associated casing section.
Claim 3
Dependent Claim
37 words
The coupling arrangement as defined in claim 1, further including two carrier rings providing the support for the support sleeve, each of the carrier rings being supported at an end of one of the associated casing sections.
Claim 4
Dependent Claim
25 words
The coupling arrangement as defined in claim 2, wherein each carrier ring is positively connected at the end of one of the associated casing sections.
Claim 5
Dependent Claim
33 words
The coupling arrangement as defined in claim 2, wherein each carrier ring is engaged between the end flange of the one associated casing section and the associated flange seal of the jacket seal.
Claim 6
Dependent Claim
28 words
The coupling arrangement as defined in claim 4, further including at least one sealing ring between each carrier ring and the end flange of the associated casing section.
Claim 7
Dependent Claim
43 words
The coupling arrangement as defined in claim 5, including a number of concentrically arranged sealing rings between each carrier ring and the end flange of the associated casing section, and wherein the jacket seal including its flange seals is of a multi-layer structure.
Claim 8
Dependent Claim
27 words
The coupling arrangement as defined in claim 6, wherein said plurality of concentrically arranged sealing rings are disposed in substantially ring-shaped grooves in the associated end flange.
Claim 9
Dependent Claim
26 words
the coupling arrangement as defined in claim 2, including means electrically conductively connecting the support sleeve with the casing sections for electrically screening the jacket seal.
Claim 10
Dependent Claim
17 words
The coupling arrangement as defined in claim 8, wherein said electrically conducting-connecting means include said carrier rings.
