ABSTRACT:
An accumulator device or the like comprising a pressure vessel having a cylindrical interior with a port at each end and an elastomeric separator or bladder interposed between the ports. An annular supporting member engages an enlarged bead at the open mouth portion of the bladder. The device is characterized by the supporting member which is in a non-critical manner bonded to the inner walls of the casing, cooperating with the bead by virtue of the special shapes thereof to coordinate with the bead and with the casing in such manner that the bead is deformed in the mounted position thereof so as to define a fluid-tight seal between the supporting member and casing. The spacing of the terminal end of the supporting member remote from the portion connected to the casing is spaced from the inner wall of the casing a radial distance substantially equal to or greater than the wall thickness of the bladder. The maximum radial thickness of the bead is between about two and one-half and three times the thickness of the wall of the bladder.
