ABSTRACT:
A hydropneumatic filament-wound pressure vessel is disclosed. The vessel includes a split tank closure and diaphragm assembly comprising a pari of cup-shaped plastic tank liners having cylindrical sidewall portions terminating in circular open mouth portions. A cylindrical ring is interposed between the open mouths of the liners and is sealed to the liners by a fusion welding operation. A cup-shaped elastomeric diaphragm is sealed to the cylindrical ring and separates the interior of the vessel into a pair of pressure chambers. The outer surface of the tank is helically wound with a resin-impregnated continuous filament.
