Abstract
Liquid and air outlet nozzle assemblies are capable of mounting on a vehicle adjacent the headlights (28) and are positioned such that liquid and air jets (106a, 110a) from the nozzles intersect prior to engaging the headlight (28) to form a spray mixture (112) that cleans the headlight (28). The nozzle assemblies are associated with a control valve (34) capable of connection in a pressurized air system (24) on the vehicle and in the pressurized washer system (16) for the windshield wipers (14) and also capable of automatically directing liquid from the vehicle washer system (16) and pressurized air on the vehicle to the liquid and air nozzles (106, 110) to form a headlight cleaning function upon manual activation of the pressurized windshield washer system of the vehicle. An embodiment of the nozzle assembly has an extension and retraction piston (122) for extending nozzle openings (168, 172) toward the headlight (28) in operation condition of the assembly.
