Abstract
A filament-wound pressure vessel is disclosed which has a reinforced access opening. The pressure vessel comprises a blow-molded one piece liner having an outer surface defined by a cylindrical sidewall and oblate ellipsoidal ends. The liner defines at least one access opening into the vessel and the access opening has a cylindrical neck portion and a liner flange extending radially outwardly from an open distal end of the neck portion. A cylindrical reinforcement member surrounds the cylindrical neck portion and has a supporting flange at one end thereof, which engages and annular face of the liner flange. The reinforcement member has a radially extending supporting foot at the other end thereof, which contacts the outer surface of the liner. The reinforcement member comprises a plurality of separable arcuate segments so that it may be assembled around the cylindrical neck portion of the liner. A resin-impregnated filament-winding covers the liner and the supporting foot of the reinforcement member.
