Abstract

PURPOSE:To prolong the life of a bladder by a method wherein the thickness of the bladder is set so that sectional areas are almost tha same at various parts in the upper and lower directions at parts excluding the clamped parts of the bladder. CONSTITUTION:The bladder 10 is molded so that its thickness increases as sections of the bladder approach the upper and lower clamped parts 10a, 10b. The thickness of the bladder is changed continuously so that the sectional areas are the same at parts throughout the upper and lower directions at sections A-A, B-B, C-C and set so that stresses are the same at all parts of the bladder.
