A wheel-shaped pressure-resistant vessel for storing gaseous, liquid or liquefied fuel and which has a substantially rigid shape. Specifically, the vessel contains a substantially continuous shell of a fiber-reinforced resin. The shell has a central opening, an inner lining and an axial reinforcement member. The shell has a substantial mechanical equilibrium shape such that the axial member is situated in a central opening. The axial member contains an inner member and two end plates, with each of the end plates fixing the shell to the inner member. Further, the axial member is attached, through both end plates, to the shell such that outer surfaces of the shell are pulled towards each other, thus reinforcing the vessel and maintaining the vessel, even while it is pressurized, in its wheel-like shape.

[ What is claimed is:] [1.] A wheel-shaped pressure-resistant vessel for storing gaseous or liquid pressurized fuel, the vessel having a substantially rigid shape and comprising:a substantially continuous fiber-reinforced shell formed of a flexible fiber-reinforced resin;a central opening;a gas-tight, substantially rigid inner lining; andan axial reinforcement member, the axial reinforcement member having a device through which the vessel can be filled with the pressurized fuel or emptied of the fuel;wherein:the shell has a substantial mechanical equilibrium shape when the vessel is in a non-pressurized condition such that the axial reinforcement member is present in the central opening;the axial reinforcement member comprises an inner member and two end plates, each of said end plates fixing the shell to the inner member; andthe axial reinforcement member is abuttingly attached through the end plates to opposing outer surfaces of the shell such that the outer surfaces of the shell are pulled towards each other, wherein, once the vessel is fully pressurized with the fuel, the shell substantially retains the equilibrium shape.
