Zusammenfassung:	A system for cleaning a sensor 205 includes a nozzle 250 directed toward a sensor window 215 and a Venturi valve 240 including a discharger 245 that is connected to the nozzle 250, the Venturi valve is connected to a fluid input valve 280 and an air source 295. Preferably the arrangement includes a computer programmed to, on receiving a determination to clean the sensor, to actuate the fluid input valve and/or the air source. The venturi valve preferably includes a suction chamber 285, an internal nozzle 290 directed to the suction chamber and a constriction zone 275 between the suction zone and a discharge. The system may include a second nozzle arrangement also directed towards the sensor window (fig 4) and may include multiple nozzles directed to multiple sensor windows.
