  • Patent number: 5045002
    Abstract: The present invention relates briefly to a jet propulsion assembly for ships, the assembly including a propeller pump of an axial or a semiaxial type. The propeller pump has a pump housing (6), the inlet of which is connected to a water inlet channel and the outlet of which is connected to an outlet device. In the water flow channel through the pump housing a pump wheel (11) is rotably journalled in a stationary casing (8). A drive shaft (12) of the pump wheel (11) extends from a drive unit through the water inlet channel to the pump wheel (11). The pump wheel (11) and the drive shaft (12) are connected by a flexible coupling (13) which is essentially torsional resistant but permits angular deviations between the drive shaft (12) and the rotational shaft of the pump wheel (11).

  • Patent number: 4992065
    Abstract: A reversing device of a jet propulsion assembly for ships. The jet propulsion assembly includes a steering means connected to the outlet of a pump, for steering the driving water jet, the steering means including two flaps for reversing the driving water jet. An actuator pivots a first flap downwards around a first bearing across the water jet, at the same time as link arms, which are journalled between the front edges of the first flap and second flap, swing the second flap around a second bearing. The rear portion of the second flap is thereby raised towards the water jet and encounters the inner side of the first flap in such a way that both flaps shut off the passage rearwards and divert the water jet obliquely downwards/forwards.
