The container (A) has an overflow valve (9), an opening (2) and a hermetically sealing cover (3), in which an outlet nozzle (7) for the outlet of the liquid is provided, which is distributed with the aid of a hose (7'). <IMAGE>

Description

', * "33420

The invention relates to a device for the pressure distribution of liquids, in particular pesticides.

In the current state of the art, no such devices are known, but devices are known

for the distribution of liquids with the help of pumps that are manual or mechanical or electrical are operated, work and fall back on solutions that have been known for some time. 10

The disadvantages which the above-described and known solutions are inherent in today on the basis of the properties mentioned are applied mainly in that these devices Not only are they expensive but also bulky, making them suitable for use in domestic or geographically restricted areas Environment are unsuitable. In addition, their installation costs are considerable, and in the case of one limited application, these expenses cannot be justified.

The object of the present invention is to provide a device of the type specified in which the disadvantages mentioned above are avoided.

According to the present invention, this object is essentially achieved in that a container is provided is, in which there is a deformable container in the form of a sack or any shape, a Opening at the top of the deformable container is provided for the liquid to be distributed to be able to fill in, as well as a connection to the pressure medium inlet on the first container in order to be able to fill up the space between the inside of the first container and the outside of the deformable container compressing the deformable container

allow and an opening in the first container and a hermetic seal on which a drainage nozzle for the liquid is appropriate.

Air or, in particular, liquid can be used as the pressure medium (Water) can be used.

The pressure distribution device according to the invention for liquids can be connected to an ordinary water hose or even be connected directly to a connection piece of a normal water network. Furthermore is a connection to a common liquid distribution system is provided, such as a Hose for sprinkling. The device can be carried along by the user or permanently installed in a specific location will.

The device according to the invention finds a special and advantageous application in the usual treatment of plants in general, for example for watering and especially for their treatment with pesticides.

The advantages resulting from the invention are preferably their low cost and simplicity Manufacturing. In addition, its operating costs are very low, since normal water pressure is used as the operating energy can be used, so that the operating costs are limited to the pure water costs. Because the device Finally, it is characterized by small dimensions and light weight, it can be easily transported and can also be easily carried by a user.

The invention is explained in more detail below with the aid of the drawing which shows a preferred embodiment explained.

It shows:

Fig. 1 is a perspective front view of the device in a preferred embodiment,

Fig. 2 shows a section along the axis X-X in Fig. 1, and

Fig. 3 is a perspective top view of a

hermetically sealing lid. 10

As can be seen from the drawing, the invention is a pressure distribution device for liquids, consisting of a metallic container A, which can also be made of plastic, and in which there is a deformable container B, which is located on the inside of the upper part 1 of the metallic container A is attached. This deformable container B extends over the entire length of the container A without touching its inside, almost to its lower end. The container A, together with the deformable container B, has an oval opening 2 on the top, as well as a hermetically sealing lid 3, which in turn is equipped with two screws 4-4 'and two associated wing nuts 5-5' to close the lid 3 fix by placing a safety rail 6 on the screws 4-4 ', which rests on the edge of the container A. In addition, this hermetically sealed cover has an outlet 7 for the liquid, to which a hose 7 'can be connected to distribute the liquid.

The container A is equipped with a connection 8, so that a pressure medium (water) into the interior of the container A can flow into the space between the inside of the container A and the outside of the container B, so that in this way the deformable

Container B is compressed.

The mode of operation is as follows: the deformable container B is filled with a liquid, for example a pesticide and water, via the opening 2. A hermetic seal is then established with the aid of the cover 3. Now can by means of a hose 8 ¹ , which is connected to a normal water connection piece C, water into the interior

.0 of the container A are introduced to the deformable

Press container B together. The water spreads in the space between the containers A and B and filled it out. As a result of the further inflow of water into the interior of the container A, the pressure rises, so that the deformable container B and thus its contents are compressed so that the liquid contained therein flows out via the outlet 7 and reaches the distributor hose T. To repeat the process, it is sufficient to empty the container A by draining the water contained in it through a drain valve 9 and refilling the deformable container B with a liquid to be distributed.

The invention is not limited to the illustrated and described exemplary embodiments, it encompasses also all professional modifications as well as partial and sub-combinations of the described and / or features and measures shown.
