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.
