Abstract

En ringformet tetning som omfatter en elastisk tetningsring (32) , en første stater (36) , en andre støter (38) som er gjengeforbundet med den første støter, gjenger (28) på den første støter for anset- tingsbevegelse av støterne (36, 38), en bruddpinne ; (40) for utløsbar befestigelse av den andre støter til den første støter, idet den første støter har en : nedre kant (64) for anlegg mot den elastiske tet- ningsring, den andre støter (38) har en nedre for- . lengelse for å utøve en belastningskraft på den elastiske tetningsring. Den første staters (36) ! anleggsareal mot tetningsringen (32) er vesentlig ¿ større enn arealet på den andre tetningsring som i utøver tetningsring-belastningskraften. I en ut- : førelse omfatter den andre støter (38) en nedre kant som strekker seg rundt utsiden av den første støter til anlegg mot tetningsringen. I en modi- i fisert form omfatter den første støter et antall åpninger gjennom sin nedre kant og den andre stø- ter omfatter et antall pinneender som strekker seg inn i åpningene for å utøve en kraft på tet- ningsringen.An annular seal comprising an elastic seal ring (32), a first member (36), a second member (38) which is threadedly associated with the first member, threads (28) on the first member for engagement movement of the members (36, 38), a breaking pin; (40) for releasably attaching the second bump to the first bump, the first bump having a: lower edge (64) for abutting against the elastic seal ring, the second bump (38) having a lower bump. longing to exert a load force on the resilient sealing ring. The First States (36)! abutment area against the sealing ring (32) is substantially ¿larger than the area of the second sealing ring which exerts the sealing ring load force. In one embodiment, the second impactor (38) comprises a lower edge extending around the outside of the first impactor abutment against the sealing ring. In a modified form, the first impact comprises a plurality of openings through its lower edge and the second impact comprises a plurality of pins extending into the openings to exert a force on the sealing ring.
