Abstract

1433522 Hydraulic accumulators J H MERCIER 1 March 1973 [7 March 1972] 10034/73 Heading F1D In an hydraulic accumulator, Fig. 1, a cap 11 is located laterally and axially with respect to a body member 10 by an annular member 26 to which a diaphragm 18 is attached. The members 10, 11, 26 are fixed together by a weld 27. Figs. 2, 2a, (not shown) illustrate the shape of the member 26 in greater detail. Figs. 3-7, (not shown), show embodiments in which the shapes of the annular member 26 and the abutting surfaces of members 10, 11 are different. [GB1433522A]
