Abstract

Forbedret, ringformet pakning (10, S) for avtetting tvers over en ringkanal mellom innbyrdes motvendte sylinderflater, og omfattende en ytterring (102) og en innerring (100) hvor spalten mellom ytterring og innerring er hensiktsmessig avtettet i en ende, slik at den åpne ende er tilgjengelig for trykk som skal avsperres mellom de to ringer, og med et ytre tetningselement (112) på ytterringens yttervegg og et indre tetningselement (108) på innerringens innervegg, hvilket bevirker at trykk som utøves mellom ringene, tvinger disse fra hverandre med tetningselement- ene i anlegg mot ringkanalens sidevegger. Ved en annen versjon av det som beskrives er det anordnet tre ringer (26, 28, 30), hvor en ende av innerringen (28) og ytterringen (26) er avtettende forbundet med enden av midtringen (30), mens ytterveggen av ytterringen og innerveggen av innerringen er forsynt med tetningselementer (36, 38) som tvinges i tettende anlegg mot ringkanalens sidevegger. En annen versjon av oppfinnelsen innbefatter ringer som varierer i tykkelse fra en ende til den annen og derved får storre eller mindre fleksibi- litet etter behov, for å kunne anpasses til trykkforårsakede bevegelser av innerdel og ytterdel.
