<P>PROBLEM TO BE SOLVED: To provide an air pressure supply device preventing noise or pollution, conserving energy, reducing its weight and cost, and having a wide variety of uses, by making an air passage communicate with an air pressure supply device to seal air. <P>SOLUTION: An air pressure supply device has a weir formed on an inner circumference of an air chamber of a doughnut-shaped bag body by fusing, a roller rotating around the center of the bag body while pushing the bag body against a frame. An air hole is formed in the bag body. Further, by installing a plurality of bag bodies of the air pressure supply device in parallel with each other and disposing and rotating the corresponding rollers on/around the same center axis, the air pressure supply device can easily respond to various requests of desired air pressure supply conditions. Since the rollers are rotated in the same direction and continuously operated, energy is conserved and a control device is simplified and thereby to solve the above problem. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
