Abstract
1412366 Hydraulic accumulators G LEDUC and M LEDUC 17 Dec 1973 [15 Dec 1972] 58242/73 Heading F1D In an hydraulic accumulator Fig. 6, in which a diaphragm 3 is held between the two halves 1, 2 of a casing, the edge of the diaphragm 3a is reinforced by a ring of hard plastics material, e.g. nylon, which fits into a recess in the diaphragm. This prevents the diaphragm being deformed and damaged under test pressures. The ring is of square or rectangular cross-section, preferably rectangular and with the height greater than the thickness. Alternatively, one or several strands of reinforcing material may be moulded into the diaphragm.
