Pressure vessel having a filamentary wound structure

A pressure vessel of a fibre-reinforced resin, which has an essentially cylindrical central portion and two domed end portions, the central portion of which comprises a tangential winding of fibre material, in which the fibre material is oriented essentially in a tangential direction, and an axial winding, located outside said tangential winding, of fibre material in which the fibre material is oriented in an essentially axial direction and the fibre material of which forms a reinforcement of the fibre material in the domed end portions;

• wherein the central portion, its tangential winding and its axial winding each have two end parts, each end part adjoining a respective end portion and formed with an internal diameter which decreases in a direction towards the respective end portion;
• wherein each end part of the tangential winding has an end facing the respective domed end portion, each said end facing the respective domed end portion having an at least substantially wedge-shaped cross-section;
• and wherein each end part of the central portion, tangential winding and axial winding, respectively, in at least substantially its entire extension forms an angle of 0.5.degree.-10.degree. with generatrices on the central portion which are parallel to an axially oriented symmetry axis of the central portion.
