Abstract

A pressurized gas tank comprises at least two cylinders and a rail capable of fluidly connecting the at least two cylinders. At least one cylinder includes a base for connection to the rail. The rail includes at least one reception area of a shape substantially complementary to a shape of the base. The base has a shape substantially revolutionary about a first axis and comprises a number at least equal to n of angularly equidistant tapped holes. The at least one reception area comprises a number equal to n of ports, in the form of an arc of a circle, angularly equidistant, of width substantially equal, by greater value, to a diameter of a tapped hole and of angular extent substantially equal to 360°/n.

First claim

The invention claimed is:

1. A tank for pressurized gas comprising:
at least two cylinders;
a rail capable of fluidly connecting said at least two cylinders, in order to form a single storage capacity, at least one of the at least two cylinders comprising a base for connection to the rail, the rail comprising at least one reception area of a shape complementary to a shape of the base, in order to be able to receive the base, wherein at least one base has a shape of revolution about a first axis and comprises a number at least equal to n of tapped holes angularly equidistant on a first circle of diameter and whose axis is the first axis, and wherein the at least one reception area comprises a number at least equal to n of ports, in a form of an arc of a circle, angularly equidistant on a second circle having a same diameter as the first circle and whose axis is the first axis, centered on the first axis, of width substantially equal, by greater value, to a diameter of a tapped hole and of angular extent substantially equal to 360°/n; and
wherein the base is pierced by a first pipe parallel to the first axis, centered on the first axis, and the at least one reception area comprises a second pipe opening out opposite the first pipe.

2. The tank according to claim 1 , wherein the number of tapped holes is equal to twice the number of ports.

3. The tank according to claim 1 , comprising a number n of screws, each screw having a shank passing through one of the ports, being screwed into one of the tapped holes and having a head resting against an outside of the port.

4. The tank according to claim 1 , wherein the base also comprises, at one end, at least one first flat surface perpendicular to the first axis, and the at least one reception area also comprises, opposite said at least one first flat surface of the base, as many second flat surfaces perpendicular to the first axis.

5. The tank according to claim 4 , wherein the base has at least one first cylindrical shape, respectively solid or hollow, whose axis is the first axis and of circular section, and the at least one reception area comprises as many second cylindrical shapes, respectively hollow or solid, whose axis is the first axis and of circular section, complementary to said at least one first cylindrical shape, the tank further comprising at least one joint, interposed between said at least one first flat surface and said second flat surface, and/or between said at least one first cylindrical shape and said second cylindrical shape.

6. The tank according to claim 5 , wherein the base has at least a third cylindrical shape, respectively hollow or solid, whose axis is the first axis and of circular section and the at least one reception area comprises as many fourth cylindrical shapes, respectively solid or hollow, whose axis is the first axis and of circular section, complementary to said at least one third cylindrical shape, the tank further comprising at least one joint, interposed between said at least one first flat surface and said second flat surface, and/or between said at least one third cylindrical shape and said fourth cylindrical shape.

7. The tank according to claim 1 , wherein the base has at least one first cylindrical shape, respectively solid or hollow, whose axis is the first axis and of circular section, and the at least one reception area comprises as many second cylindrical shapes, respectively hollow or solid, whose axis is the first axis and of circular section, complementary to said at least one first cylindrical shape.

8. The tank according to claim 7 , wherein the base has at least one third cylindrical shape, respectively hollow or solid, whose axis is the first axis and of circular section, and the at least one reception area comprises as many fourth cylindrical shapes, respectively solid or hollow, whose axis is the first axis and of circular section, complementary to said at least one third cylindrical shape.

9. The tank according to claim 1 , wherein the rail extends mainly along a second axis perpendicular to the first axis, comprises at least two sections along the second axis, traversed, along the second axis, by the second pipe.

10. The tank according to claim 9 , wherein one of the at least two sections comprises, at a first end, a first connection interface enabling the second pipe to be connected in a sealed manner and, at a second opposite end, a second connection interface enabling the second pipe to be connected in a sealed manner, and wherein the first connection interface of the one of the at least two sections is capable of being connected to the second opposite end of another section of the at least two sections.

11. The tank according to claim 10 , further comprising a first end equipment capable of being connected to a first interface and a second end equipment capable of being connected to a second interface.

12. The tank according to claim 11 , wherein the first end equipment is configured to fill the tank and the second end equipment is configured to draw from the tank.

13. The tank according to claim 1 , wherein the rail comprises a rigid body that extends along a single axis from a first end to a second end.

14. The tank according to claim 13 , wherein the rail has a polygonal cross-section.

15. The tank according to claim 13 , wherein the rail has an outer side and an inner side facing opposite of, and being parallel to, the outer side, and wherein each of the reception areas is on the inner side.

16. The tank according to claim 15 , wherein each reception area comprises the number n of ports that pass through the rail.

17. The tank according to claim 16 , wherein the number n of ports are arranged angularly equidistant about an entirety of the second circle.

18. The tank according to claim 16 , wherein there are at least four ports.
