Liquid spraying arrangement for windows
First Claim
1. A liquid spray arrangement for a window comprising a spray nozzle for directing a cleaning liquid onto a window, the spray nozzle having an inflow chamber which receives cleaning liquid, and an interaction chamber with at least one outlet opening, through which the cleaning liquid flows out of the nozzle, and an oscillator in the interaction chamber supported for pivoting motion around a pin, the interaction chamber being divided into two separate spray channels by the oscillator so that the cleaning liquid can be sprayed onto the window alternately at different angles from the two spray channels by an oscillating movement of the oscillator, wherein the oscillator is divided by the center point of the pin into an outflow end which extends toward the outlet opening and an inflow end which extends toward the inflow chamber and wherein the inflow end of the oscillator alternately closes each of the two separate spray channels.

Abstract
A liquid spray arrangement for a window has a spray nozzle which includes an inflow chamber, an interaction chamber, and an oscillator in the interaction chamber. The oscillator divides the interaction chamber into two spray channels and is caused to oscillate by the flow of a cleaning liquid, as a result of which a spray jet is sprayed onto the window alternately at two different angles. This makes it possible to increase the proportion of cleaning liquid which contributes to the cleaning of the window, and thus to reduce the volume of cleaning liquid in the storage container.
