<p>A vehicle wash, especially for cars, and comprising a portal-shaped member (2) which can be passed across a vehicle, as well as horizontal and vertical, rotatable brushes (10, 4) and driving means for moving the horizontal brush (10) along the contour of the vehicle. The wash comprises furthermore units for washing the wheels of the vehicle. Each unit comprises a horizontally scanning nozzle (28) which can simultaneously scan in vertical direction, the angular position of said nozzle (28) being adjustable in response to the direction of the movement. As a result, the washing is more efficient than the previously known. The vertical scanning is provided by means of at least one rotatably journalled link bar (30) supporting the nozzle (28) optionally through a rotatably journalled supporting member (29) and communicating with a rotatable disk (38) through a further link bar (36). The means determining the angular position of the nozzle (28) are formed by an additional link bar (32) pivotally secured to the supporting member (29) of the nozzle (28), a pneumatic or hydraulic cylinder (34) for changing the length of the additional link bar (32) being inserted in said link bar (32).</p> |
