Abstract

1477488 Hydraulic accumulators GREER HYDRAULICS Inc 29 May 1974 [30 May 1973] 23839/74 Heading F1D In an hydraulic accumulator of the type shown in Fig. 1, the diaphragm 9 has an edge reinforcement 11, Fig. 2, and an inwardly protruding bead 13. The latter prevents the diaphragm 9 from being sharply folded in the region of the edge reinforcement.
