Abstract

1,195,693. Piston and stuffing-box packing. JAMES WALKER & CO. Ltd. 13 July, 1967 [16 June, 1966], No. 26875/66. Headings F2B and F2T. In packing 1 for a piston or stuffing-box and comprising a sealing ring 2 of resilient material, e.g. rubber and an anti-extrusion ring 10 of less resilient material, e.g. synthetic plastics material engaging an end face of the ring 2, the antiextrusion ring 10 has an axially extending part 15 which engages the inner or outer peripheral surface of the ring 2. The ring 10 has a part 12 which fits in dovetail manner in a recess 5 in the ring 2. In a modification, Fig. 3 (not shown), the anti-extrusion ring (10) has parts (19) and (20) engaging the inner and outer peripheral surfaces respectively of the ring (2).
