ABSTRACT:

The present invention is directed to a pressure vessel for gaseous, liquefied or liquid materials and the like.
Pressure resistant vessels have been in use for numerous applications, one of them being the use as an LPG-container for automotive purposes. LPG is an interesting fuel for automotive purposes, i.a. due to the low price and low emission of environmentally harmful substances; hence, its use thereof has increased substantially over the last decades. However, LPG is a material that has been liquified through pressurization, with the consequence that the requirements for safety are very high. In view of their relatively low costs, generally steel pressure tanks are used for storage of LPG, the pressure tanks generally being substantially cylindrical and having torispherical domes.
A distinct disadvantage of these LPG containers is their weight and the amount of space they require in a car. In the smaller (compact) cars this weight and especially the amount of space required makes the use of LPG, as fuel, rather unattractive.
It is an object of the invention to provide a pressure vessel having a relatively low weight, and a shape which makes it better suitable for automotive applications. Another object is to provide a pressure vessel which may be used by a person carrying the vessel, for example on the back.
