Furthermore, there are parallelogram or Doppelarminwischer with an always vertical wiper blade.
  • the operation of the wiper is fundamentally always the same the same. It consists in that the wiper arm with the rubber strip attached to it moves back and forth on the disk, thus cleaning it of dirt and moisture.

  • jet stream / jet stream is not infrequent in connection with cleaning devices - such as in the cleaning of "milk pipes of all sizes” in which a designated as jet stream of water ball is shot at a speed of 12 meters per second through the milk line (Europe Dairy Systems, NL - info@europedairysystems.com).
  • Jetstreams flow components are used (taking into account the Reynolds number - as a measure in fluid dynamics, which represents the ratio of inertial to toughness forces or the ratio of specific impulse convection to impulse diffusion in System), which - quite by analogy with the meteorological term "jet stream” - a jet-oriented flow is called (DE 202009017944 Ul, DE 102008022355 AI, WO 2009135624 A2).

  • the entire disc surface is free of any disturbing movement of an object (the windshield wiper) over it. There are no losses caused by wear in the quality and effectiveness of cleaning. Since no corresponding wearable portions of a windshield wiper system are present, no replacement of the same is necessary, with the corresponding cost savings.

For example, it can emerge via slit-shaped or slit-shaped openings which are analogously placed in the edge region of the pane and can be directed onto the window front in this way.

  • the essence of the invention consists in a combination of known (nozzles, compressed air) and new elements (jet stream units, the jet stream windscreen cleaning system), which influence each other and result in a new use and the desired success in their new overall effect, the fact that with the system according to the invention soiled windows are cleaned in their entirety, the field of vision of the driver remains completely unimpaired at any time and (virtually revolutionary) the age of the windscreen wiper is terminated.
