Abstract
An oleoelastic energy accumulator includes a rigid casing, at least one membrane of a polymeric material having a high deformability, and a liquid. The membrane has a curvilinear form, e.g., convex, toward the inside of the casing to the borders of which the membrane is tightly sealed for delimiting or defining a closed space occupied by the liquid. In correspondence with the pressure variations in the liquid, the membrane acts like a piston and passes from an at-rest, curvilinear configuration, to a final substantially flat configuration as a result of gradual and successive compression of the membrane which, in this manner, accumulates energy.
