Abstract
Apparatus for washing an article, especially an automobile, comprises an article through which the article can pass, nozzles mounted on the framework, a tank provided with means for maintaining pressure therein and connected to the nozzles, a valve for controlling the flow of liquid from the tank to the nozzles and a timer. Upon actuation, the timer opens the valve for a predetermined interval, thereby allowing liquid to flow from the nozzles and wash the article passing through the framework. The pressure within the tank ensures that at least a predetermined quantity of liquid is sprayed during the interval fixed by the timer, even if the pressure in a water main supplying the apparatus fluctuates.
