Title:
CYLINDER DRIVING APPARATUS USING AIR PRESSURE
Document Type and Number:
WIPO Patent Application WO/2010/053263
Kind Code:
A2
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 fuels directly associated with global warming. Therefore, the present invention provides a cylinder driving apparatus using air pressure, with maximized energy efficiency, 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 driving 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. Further, the present invention relates to an apparatus for minimizing friction and eliminating gravitational force which may interfere with the elevating movement, to thereby maximize the efficiency of the conversion of compressed air expansion energy into rotating movement. The present invention achieves a great and active supplement to and improvement over Korean Patent Registration No. 0041791 and No. 0210368 granted to the applicant of the present invention, and proposes an inventive structure of an assistant tube that provides a novel energy source. Conventional apparatuses use a variety of fossil fuels as a power source, whereas the present invention eliminates the repeated rise of oil prices and ends energy problems, enables people to enjoy a stable life and aids in economic development, and provides all mankind with a new environmentally-friendly energy resource to take the place of the innumerable conventional power sources. The cylinder driving apparatus using air pressure according to the present invention comprises: 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 crankshaft 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/shut airflow in the upper and lower sections. The valve is shut to block the upper and lower sections from each other when the flexible tubes are filled with high-pressure air, and opens when the flexible tubes are elevated to top dead center. The valve is connected to an assistant tube, the interior of which is equipped with a tensile spring for providing spring force to keep the assistant tube compressed, to enable compressed air in the flexible tubes to flow to the assistant tube when the valve opens.
