Abstract: A cylinder driving apparatus using air pressure including: a plurality of flexible tubes arranged in a case to flexibly move via high-pressure air; a connecting rod fixed at each of the flexible tubes, and which penetrates through an upper portion of the case; a crank shaft sequentially coupled to the connecting rod to rotate via the elevating movement of the connecting rod; a high pressure tank for supplying high pressure air to the flexible tubes via an air line; and a valve arranged in each of the flexible tubes to divide the space in the flexible tube into an upper section and a lower section and to open or shut airflow in the upper and lower sections.

Abstract: It is an aim of the present invention to overcome urgent and pressing global troubles directly associated with the human right to live, such as the energy crisis, the economic crisis, and environmental pollution and the like which cannot be delayed or neglected any longer in order to meet the needs of the times. Further, it is an aim of the present invention to significantly reduce the dependency on a variety of fossil directly associated with global warming. Therefore, the present invention provides a cylinder driving apparatus using air pressure, with maximized energy, characterized in that the use of fossil fuel energy is reduced and the use of clean energy is proposed. The present invention relates to a cylinder diving apparatus in which a plurality of flexible tubes connected to a crankshaft are filled with high pressure air, alternately expand by expansion energy, and are elevated to operate and rotate the crankshaft.
