Abstract

En isolatortetning omfatter et statorelement (17) for plassering inn i det roterende utstyrs stator og et rotorelement (14) for plassering på et roterende utstyrs rotasjonsaksel. Disse to elementene tilveiebringer respektive nærliggende overflater (82, 83), og en statisk lukkeanordning (81) går i inngrep med en eller flere av overflatene når rotorelementet er i bevegelse. I ett aspekt av den foreliggende oppfinnelse er minst én av overflatene skråstilt i forhold til den langsgående akse i en vinkel på over eller under 90`. I et ytterligere aspekt av den foreliggende oppfinnelse omfatter den statiske lukkeanordning et fleksibelt ringformet tetningselement (354) og et hjelpeelement (357) som er bevegelig mellom en første posisjon, når rotorelementet er i ro, ved hvilken hjelpeelementet komprimerer det fleksible ringformede elementet inn i inngrep med begge overflatene, og en andre posisjon ved hvilken komprimeringen av det fleksible elementet reduseres, hvorved det fleksible ringformede elementet kobler fra en eller flere av rotor- og statoroverflatene når rotoren er i bevegelse.
