PCT No. PCT/GB96/01425 Sec. 371 Date Dec. 15, 1997 Sec. 102(e) Date Dec. 15, 1997 PCT Filed Jun. 14, 1996 PCT Pub. No. WO97/00398 PCT Pub. Date Jan. 3, 1997A split seal (1) having an annular cross-section and a central axis (X) comprises at least two components (2,3) of arcuate form, each component having two end portions (4,4',5,5') and each end portion having a surface (F1,F2) formed and arranged for mating engagement with a respective complementary end portion surface of another of the components. Each end portion surface (F1,F2) extends in an indirect manner over one of the radial width ( delta r) and the axial length (l) of the seal and each end portion surface (F1,F2) extends substantially continuously in non-reentrant manner over the other one of the radial width ( delta r) and the axial length (l) of the seal so that the matingly engaged components are substantially smoothly, relatively translatable in one of a generally axial direction and a generally radial direction. In a preferred embodiment each end portion surface (F1,F2) extends in a zigzag manner. |
