Abstract
En forbedret, ringformet tetning og oppheng for installering i et brøniihodehus (12). Den ringforaede tetnlngsanordning (10) omfatter en tetningsring aed en aldtseksjon (62) med et øvre og ytre randpartl (66). et øvre og Indre randparti (64) , et nedre og ytre randparti (70) og et nedre og indre randparti (68) som strekker seg utad fra aidtseksjonen, en øvre kllering (46), en nedre kllering (44) og midler som forbinder ringene med hverandre og maliggfjør deres plawierlngabevegelaø, aidler soa løsgjørbart fortoindar de ¿ammenføyde ringer med opphenget (14) for nedføring 1 brønnhodehuaet, idet hver av randpartiene innbefatter en ytre forsegllngsfllk (72) hvor de ytre forseg-' llngsfliker bar en fri dlaaeter som er mindre enn diameteren av den nedre kllering. hvorved forseglingsflikene beskyttes under opphengets nedføring i brønnhodehuaet, og midler for innføring av kileringene i rommet mellom tetningsringens randpartier. slik at tetningsflikene tvinges i tettende anlegg mot husets innvendige tetningsflate.
