Abstract (en)
[origin: EP0612657A1] The subject matter of the invention is a water-jet propulsion device for ships which are intended for use in shallow waters. A semiaxially bladed rotor (3) with a vertical axis of rotation is rotatably arranged in a well-shaped housing (1). The drive (4) for the rotor (3) is inserted into the housing from above through a cover plate, and the housing is closed at the bottom by a base plate (6) which has a water inlet (7) arranged in the centre for the axial flow towards the rotor (3) and has at least one water outlet (8, 9, 10) inclined at a small angle. Arranged between the discharge end of the feed passages of the rotor (3) and the at least one water outlet is a distributor (5) in which the water delivered by the rotor (3) is fed to the at least one outlet nozzle without the conversion of flow energy into pressure energy. The distributor forms an annular passage without blading. The water inlet (7) is of asymmetrical design. The base plate with water inlet (7) integrated in it and the at least one water outlet (8-10) is endlessly rotatable about the longitudinal axis of the housing (1) in both peripheral directions, either as part of the housing, rotatable as a unit, or relative to the housing, which in the latter case can be part of the supporting structure of the ship. <IMAGE>
