PCT No. PCT/EP94/00012 Sec. 371 Date Jul. 7, 1995 Sec. 102(e) Date Jul. 7, 1995 PCT Filed Jan. 5, 1994 PCT Pub. No. WO94/16247 PCT Pub. Date Jul. 21, 1994A gasket, which functions as a static radial seal, includes a first sealing ring disposed at a first predetermined distance from a longitudinal axis. A second sealing ring is disposed at a second predetermined distance from the longitudinal axis. The second distance is less than the first distance. The first and second sealing rings are made of metal. A common metal C-shaped casing envelopes the first and second sealing rings. The first and second sealing rings move between a relaxed position prior to installation and an engaged position after installation. The first and second sealing rings are positioned in the casing in the relaxed position and define a line that extends between the centers of the first and second sealing rings. This line is disposed at an oblique offset angle with respect to the longitudinal axis. |
