Care device for the surface ins ~

be: sonäere _i of motor vehicles -. '■: ■ "'

The innovation concerns a maintenance device for the surface. in particular of motor vehicles, consisting of a "facility" for the dosed removal of various liquid care products one container and one water each.

Devices of a similar type are already known, but have the Disadvantage is that there is no device for adding air is. That is why it is common to keep the care products in a bucket stir until a foam mixture is created by mixing in the outside air. -.-. '. _. "-

Purpose of the innovation is to avoid these disadvantages in that a maintenance device is provided, in which the container for the care products each have a selectively closable _line: are connected to a mixing nozzle, are inserted into which air and water. _:

After another suggestion after the innovation are in the Lines between the containers and the mixing nozzle, as well as in

the air conduit a respective metering valve disposed. This makes it possible to set the appropriate mixture between care products and water, corresponding to the local water quality, in particular its hardness. It is known as a care product, for example, to use shampoo to remove dirt, oil and grease and, after this layer has been rinsed off, to coat the paint surface with a protective, especially greasy layer, called a G-lancer.

An essential device of the device according to the invention is the "mixing nozzle, which essentially consists of a Venturi nozzle consists, which has an annular channel at the narrowest point, wherein the flow cross-section adjoining the annular channel downstream is larger than the one adjoining upstream Flow cross-section. This creates a particularly effective suction effect on the line opening into the annular channel exercised for care products and air =

The innovation is described below using an exemplary embodiment explained in more detail with the help of schematic drawings »

The container for the care product for removing the layer of dirt and oil, hereinafter referred to as care product 1, is denoted by 1. 2 can be a container for the paint protection layer, hereinafter referred to as care product 2. j5 is the air line opening into the ambient air »4, 5 and β denote the metering valves arranged in the connecting lines» ¹ J is a three-way valve that enables line 8 or 9 to be connected to line 10, which leads to mixing nozzle 11 . But it is also possible to completely shut off the lines 8 and 9 with the help of the tap 7, 12 is the water line coming from the water supply network, which also leads into the mixing nozzle 11 tied together. A flexible line 14, which ends in a care brush 15, is connected to the mixing nozzle 11.

In Figure 2, the mouth of the mixing nozzle is 16 and its output end designated by 17. 18 is the ring channel. In which the Lines 10 for the care product and 1j5 for the air open « 19 in FIG. 1 is a stopcock for the water pipe 12.

With the care device after the innovation it is possible., feed the following media to the care brush I5:

1. Care product 1 plus water, plus air.

2. Water plus air to remove the care product 1, together with the dirt that has been absorbed »

J. Care products 2 plus water, plus air for applying the Paint protection layer.

Needle valves are expediently used as metering valves 4 to 6 .

The addition of air makes a highly effective softer Steel creates. Another advantage of the device is that it is very easy to set up.

P.Ä. 096 666 * February 17, 1968 Nuremberg, February 14, 1968 Bu.-Sp. Re: New utility model registration Note: Heinz Ludwig, Nuremberg Protection claims 1. Device for the maintenance of the surface, in particular of motor vehicles, consisting of a device for the dosed removal of various liquid care products, from a container and water, characterized in that that the containers each have an optionally lockable. Line are connected to a 'mixing nozzle, in which further air and water are introduced. 2. Device according to claim 1, characterized in that in the lines between the containers 1, 2 and the mixing nozzle 11, as well as a metering valve 4, 5 and β each arranged in the air line is· j5. Device according to Claims 1 and 2, characterized in that that the mixing nozzle 11 consists essentially of "a Venturi nozzle consists, which has an annular channel 18 at the point, the downstream adjoining the annular channel The flow cross section of the nozzle is larger than the flow cross section adjoining the annular channel upstream. 4. Device according to claims 1 to J5, characterized in that that the lines 8 and 9 for the care products via a three-way valve 7, egg has a shut-off position, in a ge « common line 10 open. 5. Device according to claims 1 to 4, characterized in that that the common line 10 for the care products and the air line 13 at different points in the annular channel 18 of the Mixing nozzle 11 open.
