    Abstract: A pressure vessel of fibre-reinforced plastic has an essentially cylindrical central portion (10) and two end portions (11, 12) and is preferably provided with a gas-tight liner (14). The central portion comprises a tangential winding (20) of the fibre material, in which the fibre material is oriented in an essentially tangential direction and an axial winding (21), located outside the tangential winding, of fibre material in which the fibre material is oriented in an essentially axial direction and the fibre material of which extends out into and forms a reinforcement of the fibre material in the end portions. The central portion, including its tangential winding and its axial winding, in each of its parts (10a, 20a, 21a) located nearest to an end portion, is formed with a diameter which decreases in a direction towards the end portion. That part (20a) of the tangential winding having a diameter decreasing in a direction towards the end portion preferably has an end (20b) facing the end portion, the wall of the end having an at least substantially wedge-shaped cross-section.

    Abstract: A composite pressure vessel includes retaining rings at opposite ends of a side wall structure having circumferentially spaced oppositely facing tabs thereon about which longitudinal tension windings are progressively wrapped back and forth in a continuous manner around the circumference of the vessel. Between the tabs at opposite ends of the vessel are oppositely tapered ramp surfaces providing a transition for the longitudinal tension windings from a first diameter axially inwardly of the retaining rings to a second, smaller diameter adjacent the axial outer ends of the tabs, which places the retaining rings in compression in a circumferential direction. Each of the retaining rings has a generally cylindrical support surface adjacent the axial outer ends of the tabs for supporting the generally circumferential extending portions of the longitudinal tension windings thereon. The tabs have sides which taper toward each other in the direction of the axial outer ends of the tabs. Also, the radial outer surfaces of the tabs taper outwardly in the direction of the axial outer ends of the tabs, and such axial outer ends are rounded and extend generally radially and axially inwardly toward the respective ends of the vessel.

    Abstract: The invention relates to a composite pressure vessel (1) with a liner (2) made of plastic, at least one end boss (4) arranged in the region of the opening of the pressure vessel (1) and an outer layer (3) of a fiber composite material. The end boss (4) has a through hole (5) and is used for connecting a valve. The liner (2) has an axial tubular neck portion (14) with a mouth at its axial end, which extends into the end boss (4) and is provided on its outer side with an external thread (15) and a thread-free region. The external thread is screwed into an internal thread of the through hole (5) of the end boss (4).
    To optimize sealing, an inner wall of the end boss (4) in contact with the thread-free region of the neck portion (14) has at least two annular grooves (10, 11) arranged at an axial distance from one another, wherein two sealing rings (16, 17) are arranged in the annular grooves (10, 11). A first sealing ring (16) is made of a first material that seals at low temperatures, and a second sealing ring (17) is made of a second material that has low gas permeability.
