Abstract

1337549 Accumulators MOULTON DEVELOPMENTS Ltd 19 April 1971 [30 Jan 1970 4625/70 Heading F1D An hydro-pneumatic accumulator spring is formed by two part-spherical casing portions 1, 2 each having stepped and increased diameter lips 1a, 2a, the lip 2a being contracted over lip 1a to completely enclose it. A flexible butyl rubber separator has a peripheral lip 3a conforming in shape to lips 1a, 2a, the lip 3a being held by a metal ring against the inner periphery of lip 2a.
