CLOSING SYSTEM FOR VEHICLE SUPPLY SYSTEM

A closing system is provided which includes a frame adapted to be mounted on a vehicle supply system, the frame being shaped as a spherical segment and extending between a first circular section and a second circular section. The frame has a plurality of first and second guides, arranged on a radially outer surface. The closing system has a plurality of curved panels, each curved panel being shaped as a spherical cap portion and constrained at a first end and a second end thereof to slide, respectively, along a first guide and a second guide between a first position, in which the curved panels jointly define an opening that allows access to the vehicle supply system, and a second position, in which the curved panels prevent access to the supply system. Control means control movement of the curved panels between the first and second positions.
