Description of the utility model "Motor vehicle with a disk washer: file number G 69 07 557.2

Window washing devices for motor vehicles are usually provided with a spray nozzle Wse that one open "BflA" from which the stream of water comes and strikes at a certain point on the windshield. The aim is to align such spray nozzles in such a way that the water jet hits the windshield at a point as high as possible when the vehicle is stationary, so that the water flowing down can serve to wet the window. When the vehicle is moving, the wind or the dynamic pressure causes influences that reduce the effectiveness of a spray nozzle that is correctly set for the stand. The aim is therefore to find a compromise between the requirements for the direction of the water jet at different driving speeds and when the vehicle is stationary. This compromise usually leads to results which are inadequate in many areas.

Spray nozzles with two openings have also already become known. Such spray nozzles are in the center line of the Motor vehicle arranged. Jets of water emerge from them

that include a larger angle between them. You hit the windshield on two adjacent ones Places assigned to windshield wipers.

The innovation provides a solution to the problem, a windshield washer device to train for motor vehicles with a spray nozzle with two openings so that the previously described Disadvantages do not occur and a simple adaptation to all occurring driving speeds is achieved. According to the innovation, the spray nozzles on the vehicle and the two openings in the spray nozzle are arranged so that at Actuation of the windscreen washer device with two jets of cleaning fluid perpendicular to each other with a small distance on the windshield on both sides of the point meet at which the airstream is divided into a downward and an upward air flow.

The innovation is based on the observation that if the spray nozzle is set too high at higher driving speeds the water no longer runs down the windshield, but drifts off over the roof while at If the spray nozzle is set too low, the entire water flow flows downwards, while the upper area of the from Windshield wiper coated surface remains unwetted. The setting exactly at the point where the airstream is splitting into a downward and an upward airflow leads to difficulties, especially there the position of this point at different speeds

shows a certain amount of migration. The solution according to the innovation brings a considerable in a simple manner Improvement.

The spray nozzle is preferably provided with two openings, the spray directions of which have an angle of 4 to 6 Include. It has been found that such a small angle in the automotive industry The currently usual positions of the spray nozzles on the front part of a vehicle are sufficient to achieve the desired Effect is achieved.

In the drawing, an embodiment of the innovation is shown.

Fig. 1 shows the front part of a motor vehicle with a newly designed windshield washer device,

Fig. 2 shows a tubular nozzle designed according to the invention in a side view,

Fig. 3 shows the same pipe nozzle on a different scale from the driver's seat through the windshield seen.

On the front part 1 of a motor vehicle, a spray nozzle 2 designed according to the invention is attached to the usual one Place arranged. ' Two water jets 3 and 4 emerging from it at a small angle hit the wind

protective window 5. Depending on the vehicle type, there is the point at which the airflow turns into one down and one down upward airflow divides, at different heights of the windshield. The place is easy determine empirically.

Fig. 2 shows a so-called. Tube nozzle 6 in the side view. The end of the tube, i.e. the actual spray nozzle, is flattened and provided with two openings 7 and 8 through which the cleaning liquid can exit. The two Water jets shown in dotted lines form an angle c < one that is usually between 4 and 6 degrees.

Such spray nozzles can be made of metal but also of plastic. With a common nozzle for both windshield wipers, a nozzle with four spray orifices must be provided in a corresponding modification of the concept of innovation, which enclose the small angle c < in the vertical direction, while in the horizontal direction, in a known manner, a large angle corresponding to the distance between the two from the windshield wipers Include painted areas.
