Patent ID: 8690004

Claim:
An expandable storage tank attached to a traditional air compressor to generate and store compressed gas, the storage tank comprising a puncture resistant, self-sealing, flexible fabric material, wherein said flexible fabric material comprises one or more layers of fabric material, wherein said storage tank stores compressed gas at pressures between 200 and 6000 psi, the storage tank being expandable to a desired volume when inflated and when deflated, said storage tank being retractable to a compact configuration to save space compared to when said storage tank is inflated, wherein, said storage tank further comprises an exterior rigid shell that regulates the volume of said compressed gas contained within the storage tank wherein, said exterior rigid shell fully encapsulates said storage tank, wherein said exterior rigid shell is adjustable to vary the volume of compressed gas contained within the expandable storage tank to a desired volume wherein, said adjustment of volume is carried out by locking one or more buttons located on the exterior rigid shell, said buttons corresponding to a desired storage tank volume and interior pressure, the storage tank further comprising a gas compressor nozzle and pressure regulator, wherein said gas compressor nozzle attaches to and delivers said compressed gas to pneumatic power tools and equipment that require compressed gas for operability of said pneumatic tools and said equipment.
