ABSTRACT:
The invention relates to a reversing means in a marine-water-jet propulsion unit, which includes a pump (4) having connected thereto a nozzle tube (14) for directing the driving jet of water. The lower wall (14a) of the tube is provided with an opening (16), and the reversing means includes an inner flap (17) and an outer flap (18) arranged to close the opening from the inside and the outside respectively of the tube. The inner flap (17) can be swung about its fore end, as seen in the direction of flow of water through the tube, between the closed position and a position in which it is swung inwardly in the tube (14), in which position the flap (17) completely or partially blocks the flow path through the tube and deflects the water flow completely or partially out through the opening (16) in the wall of the tube. The outer flap (18) can also be swung about its fore end, as seen in the direction of flow of water through the tube, between the closed position and a position in which the flap is swung outwardly from the tube and in which the flap is directed obliquely downwardly and rearwardly, as seen in the direction of flow of water through the tube. When the outer flap occupies this open position, it directs the stream of water exiting through the opening (16) in the tube wall obliquely downwardly and rearwardly relative to the direction of flow of water through the tube. The two flaps (17, 18) have a common operating means (19, 24) for simultaneous pivoting of the flaps between their closed position and their open position (FIG. 1).
