Abstract:
This invention concerns improvements to toroidal-shaped L.P.G. tanks (1) which, due to their particular shape, may be easily placed inside the spare wheel compartment (10). In the toroidal-shaped tank described herein the hollow centre of the tank is used for positioning the valve group connection rings (3), which may either project or be flush-mounted and also for allowing the passage of the pipes (4, 5) for connecting the tank with the engine fuel supply system and the filler. The valves are placed between a lid (6), at the top, and a bottom plate (7) tide to each other in such a manner as to constitute an airtight chamber.
