Abstract

1512000 Hydropneumatic accumulators OFFSHORE-HYDRO Ltd 25 Sept 1975 [5 July 1974] 24858/74 Heading F1D An accumulator has a bladder 10 which is anchored at one end by a bead 19 and members 17, 20, and at the other end by a bolt 44, nut 52 and clamping members 45, 53. Compressed gas is admitted to the space between the bladder and the container 16 through a valve 56 and ducts 54, 55. Star-shaped members 46, 48 ensure that the bladder collapses in a pleated form. Closures 15 are provided for liquid ports 30, 32. Ribs may be moulded into the bladder to control collapse thereof.
