Abstract: A pressure vessel and a system of a vehicle with such a pressure vessel, wherein the pressure vessel is suitable for storage of pressurized fluids, comprising a housing which extends along a longitudinal axis. The housing defines an inner volume. The shape of the housing, in longitudinal cross-section, is defined by the circumference of a set of circles. The set of circles comprises a central circle, with a center point which is defined by the longitudinal axis, and four primary peripheral circles each of which intersects with the central circle at two points. The primary peripheral circles are axially distributed on the central circle in opposing pairs.

Abstract: Vessel, comprising a substantially fluid tight liner provided with a layer of fiber material, and a mount for mounting appendages to the vessel. The mount comprises a substantially cylindrical neck portion with a radially outwardly extending base flange. The base flange is axially fixedly but rotationally free held between the liner and the layer of fiber material.

Abstract: The invention relates to a fibre-reinforced pressure vessel (1, 6) comprising a rigid gas- of fluid-tight body (2, 7, 13, 19) overwound with fibre filaments (3, 10,11, 18), whereby the fibre filaments are wound such that at least a number of fibre filaments can freely move with respect to one another and when the pressure vessel is under internal pressure the fibre filaments are loaded exactly in their longitudinal direction. The invention also relates to a method of manufacturing a fibre-reinforced pressure vessel whereby no matrix material (for example, resin) is used so that at least a number of fibre filaments would be incorporated in a matrix for that section of the pressure vessel in which the fibre filaments can freely move with respect to one another.
