Abstract: The present invention comprises a cleaning system for headlamps, windshields or other surfaces, particularly of motor vehicles, comprising a tube system with liquid reservoir and a pump for providing and supplying a cleaning liquid and a nozzle configuration with liquid exit for applying a cleaning liquid of a surface to be cleaned wherein said liquid exit comprises a curved slot and/or a sphere arrangement to apply the cleaning liquid with low liquid pressure onto the surface to be cleaned.

Abstract: A de-icing system for de-icing a window pane, in particular a window pane of a motor vehicle, comprising a reservoir for receiving a de-icing liquid, a heating element for heating the de-icing liquid, a pump for pumping the de-icing liquid from the reservoir through the heating element to at least one outlet, wherein the at least one outlet is shaped such that the heated de-icing liquid is nebulized and precipitates as distributed hot droplets on the window pane to be de-iced.

Abstract: A pump arrangement for windshield washer systems of motor vehicles includes a pump housing (30) and an impeller (32) within the pump housing (30) for pumping a liquid. The pump housing (30) includes a liquid inlet (36), and a liquid outlet (38) through which the impeller (32) delivers the liquid (5) out of the pump housing (30). The pump arrangement also includes a sensor housing (40) that is connected to the pump housing (30). The sensor housing (40) includes a sensor arrangement (42, 42′) for responding to a changing liquid level (H,L) in the sensor housing (40). The sensor housing (40) has a liquid inlet (44) and a liquid outlet (46). The liquid outlet (46) of the sensor housing (40) and the liquid inlet (36) of the pump housing (30) are co-axially arranged with respect to each other.

Abstract: A spraying device for windscreen washer nozzles of automobile vehicles has a fixing body and a spraying body which are coupled coaxially to each other and to a nozzle body attachable to a body work and connectable to a cleaning liquid tube. The coupling of the fixing and spraying body forms a cleaning liquid inlet chamber, a plurality of independent intermediate chambers which lead into the inlet chamber, and an outlet chamber which links with intermediate chambers by ducts, while an outlet of the cleaning liquid in spray form is implemented through an orifice in the spraying body superimposed on the outlet chamber.
