    摘要: Hydraulically assisted fastener (10) comprises a body (11) with a central bore (12) to engage a connector element (20) and with an annular recess (14) opening outwards to an end surface (15). Annular thrust member (17) fits into and seals the recess (14). Charging medium (50) is injected under pressure into annular chamber (30) defined by recess (14) and member (17) and moves body (11) relative to member (17) to tension element (20). Medium (50) sets in chamber (30) to maintain the tension in element (20). Element (20) may be a bolt or stud, body (11) can be a nut and member (17) can be a plan washer. Medium (50) can be a curable viscous paste, a suspended solid in a self-setting compound or a particulate solid which behaves as a fluid. Suitable materials include graphite, and lead, copper or steel balls.

    摘要: A sealing device for a hydraulic assembly wherein hydraulic fluid is contained in working chamber (53) formed between body (52) and thrust member (51) of the assembly. The device comprises annular seal (63) with opposed sealing faces which are urged into sealing engagement between body (52) and thrust member (51) which have convergent sealing faces. The device may also have a pressure relief valve (100) tapped into the over-stroke end of chamber (53) to protect seal (63) from over-stroke damage comprising porous body (101) which allows fluid to bleed from chamber (53) and allows seal (63) to pass the tapping point without obstruction.

    摘要: An axially expanding spacer (10) has respective first and second spacer rings (11,12) with complementary helical ramped faces (16,17) and abutment faces (18,19). By relative rotation of the spacer rings (11,12), the height of the spacer (10), between annular faces (14,15) can be expanded or contracted. Compression springs (20) between the abutment faces (18,19) urge the spacer (10) to its “expanded” configuration.
