Abstract: A liquid ejection device for a vehicle washing facility comprises a storage volume, a first supply line coupled upstream to the storage volume for supplying a first liquid, a supply unit coupled upstream to the storage volume for supplying a second liquid, and a removal line coupled downstream to the storage volume for discharging the liquid to be ejected, with a shut-off device for shutting off liquid flow through the removal line. The storage volume is sealed so that an increase in an internal gas pressure occurs in the storage volume when liquid is introduced. The device further comprises a detection unit for detecting the supplied volume of the second liquid into the storage volume and the internal gas pressure in the storage volume, and a control unit controls the supply of the second liquid based on the detected supplied volume of the second liquid and the internal gas pressure so that a predetermined mixing ratio of the first and second liquid is achieved in the storage volume.

Abstract: A device for applying a cleaning liquid to a vehicle part includes an upper nozzle for discharging cleaning liquid in a first spray geometry delimited in a first vertical cross-section starting from the upper nozzle, by a first upper side piece and a first lower side piece that enclose a first opening angle with one another. The device also includes a lower nozzle for discharging cleaning liquid in a second spray geometry delimited in a second vertical cross-section starting from the upper nozzle, by a second upper side piece and a second lower side piece that enclose a second opening angle with one another. In a vertical projection, a first straight line extending through the first upper side piece encloses an angle with a second straight line extending through the second lower side piece is less than 10°, and the first lower side piece intersects the second upper side piece in the discharge direction.

Abstract: An apparatus for treating a vehicle surface with a fluid has a rotation device pivotably mounted about an axis of rotation, and a fluid supply device disposed concentrically with respect to the rotation device and which has an inlet opening for the supply of fluid. The apparatus is characterized in that a groove is formed in the fluid supply device. The groove is fluidically connected to the inlet opening and extends in the circumferential direction with respect to the axis of rotation over a limited circumferential angle range of the fluid supply device. The rotation device has a plurality of separate fluid channels, each of which opens into openings. The openings are disposed such that irrespective of the angular position of the rotation device to the fluid supply device with respect to the axis of rotation, and at least one of the openings of the rotation device is fluidically connected to the groove of the fluid supply device.

Abstract: A liquid ejection device for a vehicle washing system includes a reservoir volume, a first supply line coupled upstream to the reservoir for supplying a first liquid with a first supply rate and a second supply line coupled upstream to the reservoir for supplying a second liquid with a second supply rate. The device further comprises a removal line coupled downstream to the reservoir with a blocking device for blocking liquid flow through the removal line, and a detection unit for detecting liquid volume in the reservoir and a mixing ratio of the liquids introduced into the reservoir; and a removal device for ejecting the liquid found in the reservoir through an ejection element coupled to the removal line. In addition, the device comprises a control unit which is coupled to the detection unit and the removal device and is set up to start an ejection process by the removal device upon reaching a predetermined liquid volume and a predetermined mixing ratio.

Abstract: A method for treating the surface of a vehicle by means of at least one rotating treatment brush. The treatment brush comprises treatment elements, the surfaces of which are brought into frictional contact with the vehicle surface during the treatment. According to the method, a reference measurement is carried out, in which the treatment brush is set in rotation and is moved into a defined position relative to a reference element, such that the surfaces of the handling elements are brought into frictional contact with the surface of the reference element, and in this case the value of the frictional force is measured directly or indirectly. During the treatment of the vehicle surface, the treatment brush is controlled as a function of the value of the frictional force measured during the reference measurement. A system for treating the surface of a vehicle by means of which this method can be carried out.

Abstract: A vehicle treatment system includes at least one treatment device that is movable relative to a vehicle to be treated. The vehicle treatment system also includes a collision detection device for width monitoring of a maximum treatment area of the vehicle treatment system, which for monitoring a lateral boundary of the maximum treatment area has at least one first optical sensor and a control unit for evaluating output values of the first optical sensor.
