Abstract
A flexible diaphragm for a hydraulic fluid accumulator is provided with a plurality of concentric circular ridges for engagement with the wall surface of the accumulator housing between concentric circular rows of fluid discharge openings formed in the housing. The ridges maintain the diaphragm in spaced relation to the discharge openings to prevent extrusion of the diaphragm into the discharge openings.
