Abstract
Improved apparatus for cleaning vehicles includes three water lines each having a pump and a pressure regulator therein. A liquid container is connected to each line upstream of the pump, for adding liquid to the line, by a dosage metering device and a shut-off valve. Two containers are for liquid cleaners, acid and alkaline, respectively, while the third container is for water-repellant rinsing liquid. The two cleaner lines are alternatively connectable downstream of the pumps therein to a compressed air spray nozzle, while the rinsing liquid line is connectable to a separate rinsing nozzle that is also usable for drying by connection to the compressed air source.
Claims1
The vehicle cleaning apparatus comprising:
- three flow lines, each connected to a source of water;
- three containers, a first for an alkaline liquid cleaner, a second for an acid liquid cleaner, and a third for a water-repellent rinsing liquid;
- means connecting each of said containers to a respecive flow line for adding the corresponding liquid to the said line, each of said connecting means including proportionate metering dosage means and a shut-off valve;
- pump means in each of said lines downstream of the point of connection of the corresponding container therewith;
- pressure regulator means in each of said lines downstream of the corresponding pump means;
- a compressed air spray nozzle;
- valve means for selectively alternatively connecting said nozzle to said lines containing a mixture of water and liquid cleaner;
- means including a compressor for supplying compressed air to said nozzle to finely atomize the mixture of liquid cleaner and water issuing therefrom;
- and
- a nozzle detachably connectable to the line containing a mixture of water and the rinsing liquid for rinsing a vehicle subsequent to cleaning by successive applications of the two liquid cleaning mixtures by the spray nozzle and also detachably connectable to said compressed air supply for drying the vehicle subsequent to rinsing.
