Wrapper high pressure container.

The invention relates to a container

for transporting and storing items under high pressure Liquids or gases and the aim of the to be trained in such a way that the lowest possible splintering effect is achieved respectively. the occurrence of such a thing is prevented at all will. The containers can be designed in different sizes and even built as mobile or stationary large gas storage systems and dimensioned for any high pressure will.

Heretofore, generally cylindrically shaped containers have been used for this purpose, which have a relative- Massively thin wall thickness and a high-quality wire wrapping exhibit. However, since the wrapping of such a container is difficult to apply for various reasons, was also already proposed, the container a different from the cylindrical shape To give shape, but to make it axially symmetrical and with a wire winding for the purpose of increasing strength to provide. Each individual wire turn should cut the axis twice or in its like a twisting star Run past the vicinity so that the winding is perfectly even and every single turn is perfectly equal in shape and length to all others. The ones that come into question for this Container shapes are essentially designed so that their height

is not large in relation to the diameter. to an a-efes-iale To avoid displacement of the »wires is at both ends of the axis of the container where all turns of the winding pass through, attached a device through which it is possible to achieve a completely even tension of all turns.

It has now shown that in this known twisted star winding the wire gradation at the crossing points as is felt to be disadvantageous. This deficiency makes itself in particular with regard to the required tensile strength of the wire and thus the assigned solution of the task of holding the container wall tightly together, noticeable.

In order to counter this disadvantage, it is proposed according to the invention that the high-pressure container not only be one of to give a shape deviating from the forms generally used up to now, but also fundamentally to the direction in which the twist is guided to change. According to the invention, the wrapping is carried out by an opening tion or a hole in the self-contained container and the walls of the same are surrounded by a single or multiple-thread endless helix. It appears for a two-week period when »Use several coils to select the same direction of winding in opposite directions, so that net-like fields on the surface of the high-pressure container formed by the crossing wires. Such a wire wrapping with opposite winding directions is has already been used with high-pressure cylinders, but could on In this way, only the cylindrical part of such vessels are wrapped, while the other parts are still at risk. In the case of the wrapping according to the invention, the wires are capable of each other

to be removed slowly when tearing open in a crossing point, so that the high pressure vessel wall can only be torn open immediately can take place.

The figures illustrate an implementation example.

A ring-shaped, self-contained container 1

is used to hold gas or a liquid under high pressure; two wire windings are wrapped around the container. One winding begins, for example, at point 2 and runs after point 3 to the hole in the ring. From there the Wire is continued through the hole on the lower side of the container and becomes visible again at point 4 when you go from looks at the top of the container (Fig.2). The wire then becomes helical continued after a point 5 again to the hole and so on until it runs back to point 2 in itself. The second Winding starts, for example, at point 2 ', runs through the bottom of the container to point 3 * of the hole the same upwards, after 4 * on the outer circumference and from there again below to 5 * and so on, until it reaches the starting point 2 * again while maintaining this helical course.

The individual wire turns can be advantageous thin from as many adjacent turns as possible Made of wire. This achieves a high specific strength and the perfect structure of serineer wire cross-sections

largely exploited to provide increased security against violent To obtain damage to the container. Such containers have due to the full utilization of the wire strength a particularly low weight.
