The improved ring seal (1) includes an annularly shaped body element having a radial inner surface (5), a radial outer surface (6), a first axial end surface (15) and a second axial end surface (21). The ring seal (1) also includes a circular ridge (23) axially projecting from both axial end surfaces (15,21). The axial ridges (23) separate the end surfaces (15,21) into inner axial end surfaces (13,19) and outer axial end surfaces (15,21). The inner axial end surfaces (13,19) are recessed relative to the outer axial end surfaces (15,21) such that the thickness of the ring seal (1) as measured at the inner axial end surface (13,19) is thinner than as measured at the outer axial end surfaces (15,21). The ring seal (1) may further include a plurality of bores (25) which project radially inward from the radial outer surface (6) toward the radial inner surface (5). The projections of the bores (25) through the ring seal (1) from sidewalls (27) which project between the axial end surfaces (15,21) and radially from the ring seal's (1) radial outer surface (6) towards the ring seal's (1) radial inner surface (5). The addition of the bores (25) to the ring seal (1) increases the ring seal's (1) deformation during sealing compression, while the sidewalls (27) provide elastic recovery of the ring seal (1) during repeated cycles of compression and decompression. <IMAGE> |
