Title: Trykkdrevet sondetetning for et hydraulisk hunnkoblingsorgan
Inventor: SMITH III ROBERT E
IPC: F16L29/02
Filed: 2011-10-18
Abstract: En sondetetning for et hydraulisk hunn-koblingsorgan har både indre og ytre trykkaktiverte tetninger. Den ytre vegg eller motstående ender av tetningen har én eller flere trykkaktiverte tetninger for tetting mellom legemet av sondetetningen og legemet av et koblingsorgan hvor sondetetningen er installert. I visse utførelser har den generelt ringformede sondetetning et ringformet fluidkammer i én eller begge endevegger av legemet av tetningen. Hydraulikkfluid under trykk kan komme inn i det ringformede fluidkammer og utøve en generelt radial kraft som respons på en trykkdifferanse. Denne radiale kraft kan virke til å øke den tettende effektivitet av sondetetningen mot legemet av hunn-koblingsorganet som har en slik sondetetning. I "undertrykks"-situasjoner (dvs. når omgivelsestrykket overstiger det indre fluidtrykk), kan sjøvann komme inn i et ringformet fluidkammer på den motstående ende av sondetetningen og på lignende vis virke til å øke den tettende effektivitet av sondetetningen mot legemet av hunn-koblingsorganet. Ringformede, L-formede, T-formede eller vinklede spor i den indre vegg av tetningen danner hulrom og tettende fremspring som kan presses i en innover-rettet, radial retning av fluidtrykk inne i et tilknyttet hulrom for å øke den tettende effektivitet mellom legemet av tetningen og sonden av et hydraulisk hann-koblingsorgan innsatt i mottakskammeret i hunn-koblingsorganet.
