ABSTRACT:
A fluid pressure system (S) includes a flexible diaphragm bladder (172) located inside a pressure tank (164) installed within a fluid system such as well (168). In preferred aspects, the bladder (172) can be inflated by the introduction of air and is located within a flexible confining tube (198) or confining element (298) for preventing over expansion of the bladder (172). The bladder (172) and the confining tube or element (198, 298) are free floating in and without physical connection with the pressure tank (164) in preferred forms. The pressure tank (164) includes a flexible side wall (196) to allow folding or willing of the assembled fluid pressure system (S) in preferred forms. Confining tube (198) in a preferred form is of a cylindrical configuration and arranged concentrically around the bladder (172). Confining element (298) is carried by the bladder (172) and creates a barrier extending along a chord of a cross section of pressure tank (164).
