Do you have the same components as a hydraulic accumulator?
Using the large pneumatic valve storage as compensation for leakage, maintaining system pressure, controlling the action with two self-locking solenoid valve, can realize control stroke position,
The thing is, if you can't find the pneumatic components company to make one for you, now there's a lot of equipment on the device; Package: gas package is usually empty inside, just type accumulator and hydraulic sac, but there is no internal capsule, but usually the volume is greater than the accumulator volume, because the pressure of the gas is usually only about 10 kg, no hydraulic pressure, gas compression quantity is limited, only by volume to cover;
I don't know if there is a pneumatic energy storage device, but will it be able to meet your requirements based on the existing common aerodynamic elements? What kind of aerodynamic control is needed?
