  • Pressure acummulator with seal assembly
    Patent number: 4671325
    Abstract: A compression seal between opposed faces (3 & 4) of two metal members (1 & 2) comprises a metal ring (5) having a relatively thin annular web (7) and thickened beads (8 & 9) at its inner and outer peripheries defining an annular trough on each side of the web. The beads terminate in knife edges (10), washers (6) of deformable material are located on each side of the web (7) and project above the level of the knife edges (10). When the assembly is axially compressed, the deformable washers fill the troughs and any excess material is cut off as the knife edges (10) contact the members (1 & 2) thereby presenting a continuous metal surface to the exterior.
