PROBLEM TO BE SOLVED: To provide a pressure operation system which allows an optimum chamber to be easily interposed at the middle of the piping of an air-pressure circuit and operation to be controlled by using pressurized air which does not generate pulsation. SOLUTION: The pressure operation system operates control valves 102 which are continuously arranged in the piping for introducing and blocking the pressurized air following a control order in the piping 103 which constitutes the air-pressure circuit. The chamber 10 having a large capacity per unit length larger than the fore-and-aft piping is interposed at the middle of the piping has a plurality of capacity pipe members 11 having cross sections larger than that of the fore-and-aft piping, and can change its capacity by varying the number of the pipe members.
