Abstract:
Driving device for a watercraft, which device comprises a water flow channel ( 10 ) which is connected to the watercraft, preferably to the bottom thereof, and which has an inlet ( 11 ) and an outlet ( 12 ), a drive shaft ( 13, 14 ) which extends into said channel ( 10 ), a bearing shaft ( 15 ) coaxially arranged with the drive shaft part ( 14 ) in said channel, a first rotating impeller ( 21 ) connected to the drive shaft ( 13 ) for rotation in said channel ( 10 ) for the movement of water in either direction between the inlet ( 11 ) and the outlet ( 12 ), a second impeller ( 22 ) which is contra-rotating to the first impeller ( 21 ) and connected to the bearing shaft ( 15 ) for rotation in said channel ( 10 ) for the movement of water in said direction between the inlet ( 11 ) and the outlet ( 12 ), and that the drive shaft ( 13, 14 ) and the bearing shaft ( 15 ) are connected to each other via a planetary-like gearing ( 30 ), wherein one of said impellers ( 21, 22 ) is formed with an impeller casing ( 31 ) which is provided with an outer surface ( 322 ) and inside which, said gearing ( 30 ) is situated.

Claim (Index 13):
Driving device according to  claim 12 , characterized in that the first shaft part ( 13 ) and the second shaft part ( 14 ) are located on the same symmetry axis without being coaxially placed in relation to each other.
