<p>A pressure vessel for containment of CNG comprises a cylindrical body enclosed between two end domes. The cylindrical body and the domes define a convex volume and surface for accommodating the CNG. The cylindrical body has a diameter, and a length. Each of the domes has a base diameter matching the diameter of the cylinder, and an axial height. The overall length of the pressure vessel is defined by the axial length of the cylindrical body and the axial heights of the domes. The ratio between the length of the pressure vessel and the diameter of the cylindrical body is comprised in the range between one and two, or equal to one or two, so that the resulting pressure vessel looks compact, and has a good proportion of internal volume per unit surface.</p> |
