1. A gas cylinder comprising a cylinder body internally defining a gas storing space that is closable by a closure valve, in which said cylinder body comprises: a tubular wall defining said gas storing space;a bottom wall connected to a tubular wall lower end and defining the gas storing space on a cylinder lower side;an upper wall connected to a tubular wall upper end and defining the gas storing space on a cylinder upper side opposite the lower side;wherein the tubular wall comprises at least a first tubular portion that is enlarged, and at least a second tubular portion that is adjacent and narrowed relative to the first tubular portion,wherein the tubular wall has a substantially constant thickness, andwherein the narrowed portion forms a substantially cylindrical circular central ring having a constant diameter along the longitudinal axis, and two transition side rings connect the central ring to the adjacent enlarged tubular portions, wherein the side rings form circumferential steps. 2. The gas cylinder according to claim 1, wherein the tubular wall containing said enlarged and narrowed tubular portions is formed in a single piece of seamless steel, the thickness of which is formed by a single layer, with the exception of optional paint layers. 3. The gas cylinder according to claim 1, wherein the narrowed portion forms an annular narrowing defined on both sides by corresponding extended tubular portions. 4. The gas cylinder according to claim 1, wherein the side rings have, in a longitudinal section plane comprising the longitudinal axis, a double curvature or a truncated cone shape and a longitudinal extension that is smaller than the cylindrical central ring longitudinal extension. 5. The gas cylinder according to claim 2, wherein the enlarged tubular portions form circular cylindrical rings with constant diameter along the cylinder longitudinal axis. 6. The gas cylinder according to claim 2, wherein the overall longitudinal length of all the enlarged tubular portions is greater than the overall longitudinal length of all the narrowed tubular portions. 7. The gas cylinder according to claim 2, wherein said cylinder further comprises a threaded tubular neck, formed at the cylinder body so as to be able to receive said closure valve in communication with said gas storing space, and the neck comprises an inner portion internally threaded and projecting inwardly in the gas storing space in the cylinder body. 8. The gas cylinder according to claim 7, wherein the neck is formed in the cylinder body upper wall. 9. The gas cylinder according to claim 8, wherein said gas storing space forms an annular space portion about the neck inner portion. 10. The gas cylinder according to claim 7, wherein the neck inner portion is formed as a single piece with the cylinder body. 11. The gas cylinder according to claim 7, wherein the neck inner portion is manufactured separately from the cylinder body and subsequently connected thereto. 12. The gas cylinder according to claim 1, wherein the entire cylinder body is formed in a single piece of seamless steel, the thickness of which is formed by a single layer, with the exception of optional paint layers. 13. A cylinder compartment-gas cylinder assembly, comprising one or more gas cylinders, said gas cylinder comprising a cylinder body internally defining a gas storing space that is closable by a closure valve, in which said cylinder body comprises: a tubular wall defining said gas storing space, wherein the tubular wall has a substantially constant thickness;a bottom wall connected to a tubular wall lower end and defining the gas storing space on a cylinder lower side;an upper wall connected to a tubular wall upper end and defining the gas storing space on a cylinder upper side opposite the lower side;wherein the tubular wall comprises at least a first tubular portion that is enlarged, and at least a second tubular portion that is adjacent and narrowed relative to the first tubular portion,wherein the narrowed portion forms a substantially cylindrical circular central ring having a constant diameter along the longitudinal axis, and two transition side rings connect the central ring to the adjacent enlarged tubular portions, andwherein the side rings form circumferential steps:said cylinder compartment-gas cylinder assembly further comprising:a support and holding structure securable to a bearing structure of an application, and configured to at least partially receive said gas cylinders; andone or more locking members anchored to the support and holding structure and adapted to at least partially embrace said gas cylinders so as to lock them to the support and holding structure,wherein said locking members are partially received in a circumferential seat of the gas cylinder formed by the narrowed portion thereof and the enlarged portion extends in an interspace between the locking member and the support and holding structure. 14. A gas cylinder comprising a cylinder body internally defining a gas storing space that is closable by a closure valve, in which said cylinder body comprises: a tubular wall defining said gas storing space;a bottom wall connected to a tubular wall lower end and defining the gas storing space on a cylinder lower side; andan upper wall connected to a tubular wall upper end and defining the gas storing space on a cylinder upper side opposite the lower side;wherein the tubular wall comprises at least a first tubular portion that is enlarged, and at least a second tubular portion that is adjacent and narrowed relative to the first tubular portion,wherein the tubular wall has a substantially constant thickness, andwherein the narrowed portion forms a substantially cylindrical circular central ring having a constant diameter along the longitudinal axis, and two transition side rings connect the central ring to the adjacent enlarged tubular portions, wherein the side rings further comprise a double curvature shape in a longitudinal section plane comprising the longitudinal axis, and a longitudinal extension that is smaller than the cylindrical central ring longitudinal extension. 15. The gas cylinder according to claim 14, wherein the tubular wall containing said enlarged and narrowed tubular portions is formed in a single piece of seamless steel, the thickness of which is formed by a single layer, with the exception of optional paint layers. 16. The gas cylinder according to claim 14, wherein the narrowed portion forms an annular narrowing defined on both sides by corresponding extended tubular portions. 17. The gas cylinder according to claim 16, wherein the overall longitudinal length of all the enlarged tubular portions is greater than the overall longitudinal length of all the narrowed tubular portions.
