Abstract
The inventive windscreen washer jet is used for spraying front or rear windscreens of automobiles and consists of the following: a housing ( ) with a connector tube ( ) for the spray water and a chamber ( ) for integrating a jet chip ( ). Said chip has a central opening through which the water flows ( ) and from which several semicircular channels ( ) are guided outwards in a fan shape. The channels ( ) formed in the chip ( ) are open towards one end and are blocked off by the chamber walls after the jet has been inserted, so that they are watertight. The channels ( ) are formed in the chip ( ) in such a way that the width (b) of the channel narrows towards the discharge area and they have a depth of 0.1 to max. 0.2 mm and a width of 0.2 mm to max. 0.4 mm at the discharge end. This ensures that the water jet is discharged at high speed and is therefore able to wet the vehicle windscreen more effectively.
