    • Liquid and air outlet nozzle assemblies are capable of mounting on a vehicle adjacent the headlights and are positioned such that liquid and air jets from the nozzles intersect prior to engaging the headlight to form a spray mixture that cleans the headlight. The nozzle assemblies are associated with a control valve capable of connection in a pressurized air system on the vehicle and in the pressurized washer system for the windshield wipers and also capable of automatically directing liquid from the vehicle washer system and pressurized air on the vehicle to the liquid and air nozzles 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 for extending nozzle openings toward the headlight in operation condition of the assembly.
    • 液体和空气出口喷嘴组件能够安装在靠近前灯的车辆上,并且定位成使得来自喷嘴的液体和空气射流在与头灯接合之前相交,以形成清洁头灯的喷雾混合物。 喷嘴组件与能够在车辆上的加压空气系统和用于挡风玻璃刮水器的加压清洗器系统中连接的控制阀相关联,并且还能够将来自车辆清洁器系统的液体和车辆上的加压空气自动引导到 液体和空气喷嘴,以在手动启动车辆的加压挡风玻璃清洗器系统时形成头灯清洁功能。 喷嘴组件的实施例具有延伸和缩回活塞,用于在组件的操作状态下将喷嘴开口朝向头灯延伸。
