Abstract
Et tetningssystem (10) for tetting av en rørformet ledning beskrives. Tetningssystemet innbefatter et hus (16), hvor minst én ringformet tetning (22, 24) omgir husets ytre overflate. Tetningssystemet innbefatter videre minst én reservetetning (25, 26) montert på husets ytre overflate, tilstøtende den minst ene ringformede tetning. Den minst ene reservetetning har en forankringsoverflate for å gå i inngrep med den rørformede ledning. Tetnings- og forankringsaktiviseringsmidler er også tilveiebrakt for c@ drive den ringformede tetning og forankringsoverflaten inn i kontakt med den rørformede ledning som gjensvar på en aktiveringskraft. Så snart aktivisering har funnet sted, danner et første parti av den ringformede tetning en kontakttetning mot den rørformede ledning og et andre parti av den ringformede tetning trykker forankringsflaten for å bibeholde kontakt mellom forankringsoverflaten og den rørformede ledning. I den beskrevne utførelse innbefatter tetningssystemet to ringformede tetninger hvor hver av disse har en reservetetning og hvor hver aktiviseres ved hjelp av sitt respektive bladfjærsett som trykker på den ringformede tetnings bakside.
