<p><P>PROBLEM TO BE SOLVED: To provide a setting method of a bladder capable of keeping pressure balanced in and out of the bladder in a range of a predicted temperature change, a tank device with the bladder set by using the setting method and a fluid-pressure drive unit with the tank device. <P>SOLUTION: Anticipating a temperature change in operation, the bladder 3 is deformed in advance in a form capable of coping with the temperature change and attached to the tank 2. Thus, in operation, a phenomenon that the inner pressure of a working fluid chamber 6 decreases to equal to pressure or lower than the inner pressure of a gas chamber 5 is avoided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
