  • Patent number: 8726442
    Abstract: A device for supporting a side washing brush of a vehicle washing system is provided, which brush is rotatable about a rotational axis, the device including a bearing apparatus for rotatably supporting a drive shaft, and a holding apparatus which is fixedly connected to the bearing apparatus and which is held on a frame by means of elastic cushioning elements arranged above and below the holding apparatus. To improve the device in such a way that the risk of damage to the cushioning elements is reduced, it is proposed that the holding apparatus can be acted on by the cushioning elements only by compressive forces aligned in the direction of the holding apparatus. A vehicle washing system is also proposed which has at least one device of this type, on which a side washing brush is mounted.

  • Patent number: 8464385
    Abstract: A vehicle washing installation is provided having a first and a second support on which at least one treatment tool is mounted in a height-adjustable manner by means of a first and a second carrying means, and having a carrying means drive device from which the carrying means extend to the treatment tool via deflection elements situated on the top of the supports, one carrying means extending above the treatment tool from at least one deflection element situated on the first support to at least one deflection element situated on the second support. To improve the vehicle washing installation in such a way that it may be easily adapted to the height of a washing bay, it is proposed that the deflection elements are mounted on intermediate parts which are fixable to the supports at different vertical positions.

  • Patent number: 7922565
    Abstract: The invention relates to a device for comminuting dry ice granules, comprising a housing having a flow channel for dry ice granules which can be applied, by means of compressed gas, to a surface to be cleaned, and also comprising a first comminution member for comminuting the dry ice granules which are to be dispensed. In order to provide a device of this kind with which different degrees of comminution of dry ice granules can be achieved in a simple manner, it is proposed according to the invention that the device has at least one second comminution member which can be disposed in the housing in a position in which a total degree of comminution, which is greater than the individual degree of comminution which can be achieved solely by the first comminution member, can be achieved in combination with the first comminution member. A dry ice dispensing arrangement for dispensing a mixture of compressed gas and dry ice granules is also proposed, having a device of the above kind.
