Car washing installation
First Claim
1. Vehicle washing installation, in particular for vehicles with a very rugged surface, comprising several spray nozzles for a cleaning liquid possibly with chemicals added thereto arranged next to one another transversely to the longitudinal direction of the vehicle along a portal and moved past said vehicle in the longitudinal direction of said vehicle, said spray nozzles (20) being designed as rotor nozzles which deliver one point contact jet each, said point contact jet issuing at an acute angle of up to approximately 30 degrees at the most at an incline to the axis of rotation of said rotor nozzle and describing the lateral area of a cone, characterized in that said spray nozzles are movable back and forth along the portal around a vehicle in a plane lying transversely to the longitudinal axis of said vehicle, the amplitude of the motion of neighboring spray nozzles (20) being at least so large that the parts of said vehicle (5) over which their point contact jets repeatedly pass ajoin one another.

Abstract
A car washing installation has several jet nozzles (20) for a cleaning fluid, if necessary mixed with chemical substances, arranged one next to the other transversely to the length of the car and moved past the car in its longitudinal direction. The jet nozzles (20) are designed as rotative nozzles that supply a point contact jet that emerges from the rotative nozzles at a maximum acute angle of about 30° in relation to the axis of rotation of the nozzles. To ensure that all car surfaces are reliably cleaned, even when the car has a rugged surface, characterized by recesses, the jet nozzles (20) can be periodically moved along the profile of the car on a perpendicular plane to the longitudinal axis of the car.
