Abstract

1316841 Piston packing HALLITE HOLDINGS Ltd 19 April 1971 [31 March 1970] 15247/70 Heading F2T Piston packing comprises an elastomeric sealing ring 3 having a portion 5 tapering toward the cylinder 1 and axially located between and abutting two rings 6 of material harder than that of the ring 3, which ring is of a conformation such that it can be stretched to be fitted over the piston head. The ring 3 is housed in a groove 4 in the piston 2 and each harder ring 6 is housed in a shallow groove 7 and has a frusto-conical end face 8 abutting the tapered portion 5 of ring 3. In a modification, Fig. 2, the harder rings 10 have flanges 11 abutting the ends of the base portion of the sealing ring 9 and housed therewith in the groove 4. The sealing ring may be of nitrile rubber, polyurethane, neoprene, fluorocarbon or ethylene propylene and the harder rings, which may be split, may be of steel, cast iron, brass, nylon, acetate resin, fabric-reinforced rubber or phenolic resin.
