Diaphragm accumulators have a rubber plate or diaphragm as the separating element. This element is either welded or screwed together between two spherical shells (or compartments). The compartment above the diaphragm is filled with nitrogen. The compartment below is directly connected to the hydraulic circuit. Diaphragm accumulators are the smaller of all hydraulic accumulator types and available at fluid storage capacities of 0.075 to 4 litres.
