Abstract

En utvidbar tetningsanordning (16) innbefatter et elastomert rørformet legeme (22) og en ytre kappe (24) som omgir legemet (22). Et endeelement (30) er også anordnet som har en lokkdel (32) l gjengelnngrep med et ringformet element (34), der ringelementet (34) er festet til endepartiet (36) av den ytre kappe (24). Et antall forsterkende elementer (28) er klemt mellom kappen (24) og legemet (22) og har endepartier (54) som avslutter under ringelementet. Tilslutt er det en mekanisme (60) til å forkile endepartier (54) av de forsterkende elementer (28) mot den indre flate (66) av ringelementet (34) som reaksjon på øket gjengeinngrep mellom lokkdelen (32) og ringelementet (34) for å bibeholde elementene (28) i stilling under ringelement- et (34).An expandable sealing device (16) includes an elastomeric tubular body (22) and an outer sheath (24) surrounding the body (22). An end member (30) is also provided having a locking member (32) in a threaded engagement with an annular member (34), the ring member (34) being secured to the end portion (36) of the outer sheath (24). A plurality of reinforcing members (28) are sandwiched between the sheath (24) and the body (22) and have end portions (54) terminating below the ring member. Finally, there is a mechanism (60) for disengaging end portions (54) of the reinforcing members (28) against the inner surface (66) of the ring member (34) in response to increased thread engagement between the lid member (32) and the ring member (34). retaining the members (28) in position below the ring member (34).
