Abstract
A split tank closure and diaphragm assembly for a hydropneumatic filament wound pressure vessel is disclosed. The assembly includes first and second cup shaped plastic tank liners having oblate ellipsoidal end portions and cylindrical sidewall portions terminating in cylindrical open mouth portions. A ring is provided for joining and sealing the open mouth portions together to form a sealed container and to mount a diaphragm within the tank to divide the interior of the tank into variable volume chambers. The ring has a cylindrical outer surface corresponding to the outside diameter of the cylindrical sidewall portions of the liners. The liners form a dovetail joint with the ring and respectively trap an O-ring and a bulbous portion of the diaphragm between recessed portions of the liner and a surface of the ring to seal the interior of the tank. The assembly is wound with a resin impregnated continuous roving to reinforce the tank and resist internal pressures.
