Abstract
A pressure vessel includes a main portion bounding an internal chamber for accommodating a pressurized fluid medium, and a hollow stem portion projecting from the main portion and bounding a passage communicating with the internal chamber. The vessel walls are formed by an inner liner that extends into the stem portion, and a fiber reinforced outer jacket overwrapping a main portion of the liner to confer structural strength to the main portion of the vessel. A fitting axially adjoins the stem portion and is secured thereto by a strengthening body that is situated externally of and engages the stem portion of the liner and an axial portion of the fitting, and the strengthening body being anchored to the outer jacket. The axial portion of the fitting has an external projection or ring that is firmly engaged by the strengthening body to prevent at least axial movement of the fitting relative to the stem portion of the liner. The strengthening body may either be a fiber reinforced body wrapped around the stem portion of the liner and the axial portion of the fitting, or the combination of a split sleeve having an integral anchoring portion anchored between successive layers of the outer jacket and a main portion surrounding the stem portion of the liner and the axial portion of the fitting, and a tightenable ring that surrounds and engages the main portion of the split sleeve.
