The method of forming a pressure accumulator which comprises the steps of molding the mouth of the deformable separator or bladder of the pressure accumulator to one end of the cylindrical portion of an annular supporting member, inserting the annular supporting member and bladder into the open end of a cylindrical casing with the cylindrical portion of the supporting member in juxtaposition with the inner surface of said casing, said casing having the other end thereof deformed inwardly and having an axial port, fusing the other end of the cylindrical portion to the inner surface of the casing and then deforming inwardly the open end of the casing to close the latter and forming an axial port in such closed end to receive a gas charging valve.
