Abstract
An elastomeric bladder for dividing a pressure vessel into two chambers is formed in one piece and carries integrally at least one rigid element (18 or 19). A tubular blank bladder 10A of raw elastomer is shaped in a mould by fluid pressure applied to the interior of the blank while the rigid elements 18, 19 are clamped against the ends E1, E2 of the bladder valve and a vulcanization is performed whereby the rigid elements 18, 19 are bonded to the bladder.
