  • Pneumatic engine system with air circulation
    Patent number: 9068455
    Abstract: A pneumatic engine system uses gas circulation to recycle exhausted air, so as to reduce gas consumption, save energy, protect the environment, operate for a longer duration, and slow down the attenuation of the power output thereof. The pneumatic engine system includes a pneumatic engine, a gas storage device, a transit gas storage tank, and a suction device. The pneumatic engine receives a compressed air to generate power output. The gas storage device stores the compressed gas and supplies the compressed gas to the pneumatic engine. The transit gas storage tank receives gas discharged from the pneumatic engine. The suction device extracts gas from the transit gas storage tank and transport the extracted gas to the gas storage device for recycle.
