1. An automobile vehicle ( 1 ) having a bodywork ( 2 ) in which a member or panel (W) is mounted and is operationally cleaned without wipers, a frame ( 3 ) being associated with its perimeter or contour, the surface of the member or panel (W) which is external in operation being water-repellent, and ejector means (A, B) being associated with the member or panel (W) in order to direct a plurality of jets of fluid towards its external surface,

characterized in that the ejector means comprise

a first plurality of openings or nozzles (A) for the discharge of a liquid provided in the frame ( 3 ) such that each side of the frame ( 3 ) comprises at least one opening or nozzle (A), the openings or nozzles (A) being oriented towards the external surface of the member or panel (W),

a second plurality of openings or nozzles (B) for the discharge of a gaseous fluid also provided in the frame ( 3 ) and interspersed with the openings or nozzles (A) of the first plurality such that each side of the frame ( 3 ) comprises at least one opening or nozzle (B) for the discharge of a gaseous fluid,

at least a first manifold duct ( 5 ) provided in the frame ( 3 ) and communicating with at least part of the liquid discharge openings or nozzles (A),

at least a second manifold duct ( 6 ) provided in the frame ( 3 ) and communicating with at least part of the discharge openings or nozzles (B) of the second plurality,

the first and second manifold ducts ( 5 , 6 ) being connected to respective supply means ( 10 , 14 ) adapted to supply them with a flow of liquid and a flow of gaseous fluid respectively,

the arrangement being such that in operation the preferably combined action of the jets of liquid and gaseous fluid emitted through the openings or nozzles (A, B) is adapted to cause a turbulent movement of the liquid on the external surface of the member or panel (W) and of the materials which may be incorporated in this liquid.

2. An automobile vehicle according to claim 1 , wherein the frame ( 3 ) is provided with a plurality of manifold ducts ( 5 ) for liquids which may be connected to respective openings or nozzles (A) in order to enable a plurality of liquids having different chemical and/or physical properties to be ejected towards the member or panel (W).

3. An automobile vehicle according to claim 1 , wherein the frame ( 3 ) is a gasket for sealing and/or mounting the member or panel (W) in the bodywork ( 2 ).

4. An automobile vehicle according to claim 1 , wherein the frame ( 3 ) is of metal material.

5. An automobile vehicle according to claim 1 , wherein the frame ( 3 ) is integral with the bodywork ( 2 ).

6. An automobile vehicle according to claim 1 , wherein the external surface of the member or panel (W) is provided with a nanostructured transparent film such that it has hydrophobic properties.

7. An automobile vehicle according to claim 1 , wherein a layer of fragmenting nanopowder, which may be activated by electrical pulses, is deposited on the external surface of the member or panel.

8. An automobile vehicle according to claim 1 , wherein nanomotor devices adapted to move micro and nano particles deposited on the surface of the member or panel (W) are associated with the external surface of the member or panel (W).

9. An automobile vehicle according to claim 1 , wherein rain sensors ( 4 ), made from films deposited on the member or panel (W), are associated with the member or panel (W).

10. An automobile vehicle according to claim 1 , wherein a crossbar ( 16 ) is disposed in front of the member or panel (W) in order to direct a flow of accelerated air towards the member or panel (W) when the automobile vehicle is in motion.

11. An automobile vehicle according to claim 10 , wherein the member or panel (W) is a windscreen and a further crossbar ( 30 ) is disposed in the vicinity of its upper end and is adapted to impede the tendency of the sheet or layer of air which strikes the windscreen in operation to move or lift away from the surface of the windscreen (W).

12. An automobile vehicle according to claim 10 , wherein the crossbar ( 16 ; 30 ) is provided with openings or nozzles for the supply of jets of liquid and/or gaseous fluid towards the external surface of the member or panel (W).

13. An automobile vehicle according to claim 12 , wherein the openings or nozzles of the crossbar ( 16 ) are connected to manifold ducts ( 5 ′, 6 ′) disposed within the crossbar ( 16 ) and preferably connected to the supply means ( 10 , 14 ) connected to the manifold ducts ( 5 , 6 ) of the frame ( 3 ).

14. An automobile vehicle according to claim 1 , wherein the member or panel (W) is associated with at least one spray device ( 19 ) disposed in the vicinity of one side of the member or panel (W) and adapted to direct a flow of fluid towards the external surface of the member or panel (W).

15. An automobile vehicle according to claim 1 , wherein the member or panel (W) is a windscreen, a rear window, a fixed or moving pane of a window or a roof panel which is at least partially transparent, or another member with a glazed surface of the automobile vehicle.

16. An automobile vehicle according to claim 1 , wherein the member or panel (W) is a windscreen which is shaped such that it has an aerodynamic configuration with triple curvature.

17. An automobile vehicle according to claim 10 , wherein the member or panel (W) is a windscreen and the crossbar ( 16 ) is shaped in the form of an upturned aerofoil.

18. An automobile vehicle according to claim 11 , wherein the further crossbar ( 30 ) is shaped in the form of an aerofoil.
