The present invention relates to a multi-chamber tank for compressed gas with a modular design, which allows you to carry it with variable volume and capacity in accordance with the application and installation location of the tank.

Although the principal application of this tank are the vehicles running on natural gas, it should be understood that the tank can be used for storage of any type used in the technique of gas under high pressure.

The tank according to the invention represents an alternative solution to the traditional steel cylinders cylindrical shape having several advantages, such as higher degree of safety in operation, more than just doing an internal examination during retesting, less weight, higher degree of flexibility from the point of view of form and volume with the same capacity.

The hallmarks of the tank according to the invention is determined by its basic design, according to which the total capacity of the tank creates numerous cylindrical chambers arranged in parallel with the ability to message each other and implemented in the form of groups of thin-walled tubes, which are attached to the mechanical strength with an outdoor usilivaya what about the coverage of composite materials with resins.

More precisely, the tank according to the invention contains a group of tubes resting on spacer plates with parallel, closely spaced rows of holes, suitable for accommodation of similar tubes installed in such a way that each tube is almost in contact with adjacent tubes to reduce the size.

The group of tubes immersed in a fibrous resin, which fills all the gaps in the group of tubes to the level of the borders of the spacer plates.

The two ends of the group of tubes hermetically closed by two end caps on the inner side of which is formed of a number of communicating with each other, a hemispherical dome-shaped notches that correspond exactly to the holes of the tubes in the group.

The two end caps attached to the group of tubes by means of tie-rods passing through the gaps in the group of tubes.

The group of tubes, immersed in a fibrous resin, attached to the resistance by wrapping her glued with resin cloth with a continuous wire, on which is superimposed a second fabric bonded with resin longitudinal wires to connect the two caps.

The tank according to the invention placed in an appropriate, pre-formed protective cover, preferably made of sheet aluminum.

Based on the description of the layout of the tank, it is possible in order to show the advantages of the tank according to the invention, which become apparent in relation to traditional steel cylinders Zilinskas form. First of all the tank according to the invention can be shaped in different forms by selecting the appropriate number of tubes for each side around the perimeter.

The length of the tank can be changed by simply varying the length of the tubes in the group.

In addition, the tank according to the invention is distinguished by the ratio of capacity to weight due to the low specific weight of the materials used, i.e. thin-walled metal tubes and fibrous resins, low specific gravity and a large mechanical stretch resistance.

With regard to the small wall thickness of metal tubes, it should be noted that you do not want the tube had good mechanical strength, whereas the outer coating of the fiber resin reinforced cloth with wire, passing in the transverse and longitudinal directions.

In other words, the tube only the function of education in a number of cylindrical cavities, which must be obtained in the frame of the tank is formed from a fibrous resin.

A higher degree of operational safety of the tank according to the invention due to the fact that persistent surface of a tank containing compressed gas, increased by CPA is to containers of cylindrical shape, having the same capacity, resulting in reduced mechanical stress occurring in the surfaces.

With regard to more than simply perform internal inspection of the tank, it should be noted that the group of tubes can be inspected from the inside and cleaned at any time after removing the two covers. After completion of the inspection and maintenance operations two caps set in place, and the tank may be subjected to the tests.

At the present time for the purpose of internal inspection internal cavity of the cylinder cylindrical visually inspected through the opening, into which is inserted a valve for injection of gas, after dismantling. This means that the inspection is carried out through a small hole with a diameter of 3/4 inch, which is not enough to ensure the absolute reliability of the control operation, the purpose of which is to check the integrity of the internal wall of the container has a cylindrical shape.

To ensure full clarity the following description of the tank according to the present invention with reference to the attached drawings, which are intended for purposes of illustration and should not limit the invention and depicting the following:

figure 1 is a view of a tank having the form of a rectangular parallelepiped and a rectangular base;

Fig.9 is a view of the tank of another form.

As shown in the attached figures, the tank 1 according to the invention contains a group 2 thin-walled tubes resting on spacer plates 3 with parallel, closely spaced rows of holes 3A, suitable for accommodation of similar tubes 2A installed in such a way that each tube 2A is almost in contact with adjacent tubes, as shown in figure 3, to reduce the size.

Group 2 tubes immersed in a fibrous resin 4, which fills all the gaps in the group of tubes, including the intervals in the peripheral zone where the resin comes just before the border is exactly at the level boundaries) spacer plates 3, as shown in figure 4.

The two ends of the band 2 tubes hermetically closed by two end caps 5, on the inner side to the is that there are a number of hemispherical dome-shaped grooves 5A, communicating with each other through channels 5b and exactly corresponding to the hole tubes 2A in the group, as shown in the enlarged view on figa.

Two cover 5 is attached to the group 2 of the tubes by means of tie-rods 6, passing through the gaps in the group of tubes and through the holes 3b, respectively, performed on the spacer plates 3.

Group 2 tubes, immersed in a fibrous resin 4, given the strength and stability by wrapping her glued with resin cloth 7 continuous wire, as shown in figure 5.

The second fabric 7a only with longitudinal wires superimposed over the first fabric 7 to attach the lids 5, installed and pressed to contact via couplers 6 group 2 tubes, as shown in Fig.6.

The tank according to the invention placed in an appropriate, pre-formed protective casing 8, preferably made of sheet aluminum, as shown in figure 1.

One of the caps 5 are made with a hole for the gas valve, which is a gas valve of conventional type and therefore not shown in the attached drawings.

You should specify that the gas valve can be installed in the most comfortable position in the cover 5, because all of a hemispherical dome-shaped grooves 5A are connected with each other through channels 5b, and therefore, the gas containing the action scene in the tubes 2A, can reach to the valve through a grid of communicating with each other dome-shaped grooves 5A.

Fig.9 is applied with the sole purpose to illustrate the execution of a tank according to the invention with any shape, including irregular shapes, in accordance with form in space, where installing the tank.

This hallmark of the tank according to the invention is extremely useful in the case of tanks for natural gas, installed in the trunks of vehicles. The tanks are cylindrical in shape, which are currently used for this purpose, have a small container because they can't "use" the available space in the best way, because it is impossible to perform the cylinders with the appropriate shape and size that will fit the space in the trunk, where the tank is usually installed.
