Abstract: The invention is a combination accumulator and reservoir which stores energy when the accumulator deforms from its original shape in response to the flow of a pressurized fluid from the reservoir. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid and returns to its original shape. At least one part of the novelty of the invention is that the accumulator and the fluid reservoir reside in the same housing such that the volume of each varies inversely. Accordingly, the invention is more compact and weighs less than conventional accumulators. Another feature of the invention is that fluid is located around the bladder accumulator to lubricate contact between the bladder and sides of the reservoir.

Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.
