Purely the transport of perishable goods such as fruits, vegetables, Meat, fresh fish, eggs, dairy products, flowers and the like over long distances are refrigerated and Protection of goods against spoilage and damage to the load is of great importance. So far this will be the case Loads transported in large refrigerated wagons or refrigerated wagons. Frequent reloading is required for this. The cold chain is interrupted many times, so that the valuable goods spoil. It now became a Smaller container - also known as a container - has been developed that has its own unit to handle the transported goods to protect. A base body has hinged side walls the space in between is then covered with a heat-protective tarpaulin. At At least one, but preferably both side walls are arranged elements that the intermediate Cool room. They can be used for cooling and / or protection and / or to continue the Release gases during the maturation process. The one for the cooling unit ' and / or the media required for treatment stored in the main body, for example in liquid form in bottles. It comes mainly from nitrogen and Oxygen in question. The side walls can be folded down to close the transport container with as little space as possible transport free of charge and / or at least under the terms of the railways and other transport companies to be able to transport them back. The media for cooling and / or treatment must, in order for them to be connected are available in the right places and can be handed in if necessary »in the folding side walls be guided.

There is a risk of being present in form and therefore flowing through the required line at extremely low temperatures freezing or blocking of the necessary taps and Slewing rings. It must therefore be seen to use such taps and swivel joints that are in the cold and icy condition are still functional and ^ run smoothly.

Because of the medium supply to be stored in such a container due to the small space and the transport weight is limited and on the other hand causes costs for the transport, it must be taken into account that no medium is lost. It must therefore be ensured that · a medium outlet in the unused closed State does not occur.

The invention is based on the object of making available an arrangement for such a container and possibly other uses which, with a simple, operationally reliable structure, causes automatic closing when pivoting. According to the invention it is provided that a gas-tight rotary connection and a shut-off valve are arranged in the line between the base body and the side wall, and that the shut-off valve housing and closure element are coupled to the base body and the side wall in such a way that the shut-off valve is open when the side wall is opened and closed when the side wall is closed is. Coupling the tap with the pivoting movement ensures that no medium is lost, at least when the container is closed. If desired , taps and control devices can also be provided for the setting in the opened state. . .

509812/0250

In order to avoid flexible or slidable connections, the axis of the rotary joint is always included align with the axis of the hinge, especially since the slewing ring does not take up as much space as a Faucet. If it is not possible for reasons of spatial dimensions to also arrange the tap so that the The pivot axis of its actuator coincides with the axis of the hinge, so you can do this too Arrange outside the * hinge axis in the housing and then a corresponding transfer to its actuator with hinges or movable, if necessary Provide sliding elements.

Particularly advantageous because it is simple and can be implemented without transmission and sliding elements, the arrangement can be made in that the rotary connection, the shut-off valve actuator and the hinge of the foldable side wall can have a common axis. Since a rotary connection and a pivotable side wall are provided here, it is also expedient to provide a shut-off valve with a rotatable closure member through which the line passes and which is the rotatable part of the rotary connection. This results in a unit of shut-off valve and rotary joint that is particularly simple in structure and, above all, in assembly, so that puncture defects due to assembly inaccuracies are reduced to a minimum. In addition, the unit is particularly simple in structure in that a shut-off valve with a rotatable closure member already has a rotatably sealed part so that this can be used directly for connecting the line. Such a unit can be built particularly small and in thin side walls or the like even in tight spaces. be well accommodated

The mentioned container works perfectly with media stored at very low temperatures, but also in other applications where it is important to combine the opening and closing movement with a rotary joint, it can be constructed in such a way that the shut-off valve is a known ball valve, whose locking ball is mounted in sealing and retaining disks and is rotatably coupled to an actuating element that is sealed and rotatable through an actuating element bore running transversely to the main bore for the installation of the locking ball and the supply of the medium, which has a bore that is open to the interior of the locking ball and outside of the stopcock housing has a pipe connection for the bore. In one position the ball blocks the inflow to its interior and also to the environment, while in the other position the inflow to its interior is open and the outlet can thus take place via its bore through the adjusting element. A particular embodiment of such a shut-off member, which is on the one hand so constructed that it _s is smoothly designed and on the other hand, as also in the frozen state and the temperature expansions extremely low temperatures still functional, that it is simple to manufacture and assemble, may be constructed to that the locking ball in a known manner; at the by 90 degrees; to the axis of its through-hole forming the interior dome has a recessed slot into which a switching cam of the actuating element engages with little play and through the bottom of which a hole leads to the interior of the locking ball and whereby the bore of the actuating element ends in the switching cam. The holes are opposite each other. Due to the sealing of the ball on its sealing and retaining washer facing the inlet, no more medium can enter the

Get cams surrounding space.

In order to seal such known ball valves well and to keep them easily rotatable at low temperatures, are Adjusting elements with an internally formed flange are used, the length of which is such that they can be removed from the inside can assemble. With the pipe connection screwed on, this is necessary for setting the seal Parts no longer possible. You can therefore provide an easily assembled unit so that the adjusting element has formed a sealing flange in a manner known per se on the end carrying the switching cam and that on the opposite side of the main bore .a lockable insertion and assembly bore for the Control element is provided.

On the one hand, the seals of the control element exactly. . "and to be able to readjust and on the other hand the pipe connection in the respective B required Position properly sealed to fix and also, if necessary, the adjusting element with the pivotable To couple part properly, the adjusting element can be located between the sealing nuts provided on the stopcock housing side and the pipe connection have a key flat. So that the switching force when pivoting does not need to be applied over the pipeline, a key can be used with the Attack pipe connection having moving part of firmly connected driver.

Often you will not be able to use the special valve described above or for economic reasons don't want to use. It can also be for reasons of the passage cross section or other sealing and
