Abstract
A vehicle wash system having a nozzle for directing a spray of a fluid wash medium at a vehicle for washing the vehicle in which, after the vehicle has passed the spray path, the fluid spray contacts a switch on the opposite side of the vehicle wash that is aligned with the spray path to actuate the switch. The switch is used to shut-off the fluid spray.

In a vehicle wash system defining a path of travel for a vehicle to be washed and having a spray nozzle for directing a wash medium along a spray path at a vehicle moving along the vehicle path of travel, pump means for selectively supplying the wash medium to the nozzle and control means for actuating the pump means, the improvement comprising a shut-off switch in said control means having on and off modes corresponding to on and off modes for the pump means, the switch being biased to the on mode wherein the pump means supplies the wash medium to the nozzle and the switch being located opposite from the spray nozzle along the spray path such that the vehicle traveling along the vehicle path of travel passes between the nozzle and the switch intersecting the spray path and after the vehicle has passed the spray path, the impact of the spray of wash medium from the nozzle contacting the switch places the switch in the off mode to stop the pump means and thereby stop the spray of the wash medium from the nozzle.
A vehicle wash system comprising:
- means for defining a path of travel for a vehicle to be washed;
- a first spray nozzle for directing a wash medium along a first spray path at a vehicle moving along the vehicle path of travel;
- pump means for selectively supplying the wash medium to the first spray nozzle;
- and
- control means for actuating the pump means, the control means including a shut-off switch having on and off modes corresponding to on and off modes for the pump means, the switch being biased to the on mode wherein the pump means supplies the wash medium to the first spray nozzle and the switch being located opposite from the first spray nozzle along the spray path such that the vehicle traveling along the vehicle path of travel passes between the first nozzle and the switch intersecting the spray path and after the vehicle has passed the first spray path, the impact of the spray of wash medium from the first spray nozzle contacting the switch places the switch in the off mode to stop the pump means and thereby stop the spray of the wash medium from the first nozzle.
