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.
