ABSTRACT:
A vehicle wash system is disclosed which consists of an arch through which a vehicle can be moved. A plurality of spinning nozzle assemblies are attached to the arch each having a number of nozzle outlets for directing the water to the vehicle surface to remove dirt, salt, etc. in which only water impacts the vehicle. The nozzles are oriented so as to create a rotational moment to spin the nozzles relative to the nozzle assembly. An oil pump is contained within the assembly to provide a resistance to rotation to regulate the speed of nozzle rotation. Each water nozzle includes an air nozzle to form a sheath of air around each water jet to maintain the integrity of the water jet to maximize the water jet impact force with the vehicle surface.
