Waterjet propulsion unit for water craft with control elements for changing the direction of thrust of the waterjet

摘要

Water jet propulsion unit for watercraft having a pump and stators arranged upstream and downstream of the pump for eliminating turbulence in the entering water and in the water jet generated by the pump, having coaxially arranged nozzles which are associated with the respective stator and are supported so as to be displaceable axially independently of one another, and having a switchable gear unit for driving the pump in the clockwise or counterclockwise direction in order to change the direction of motion of the watercraft, the water jet propulsion unit being supported at the watercraft so as to be swivelable by .+-.90° approximately vertically to the axis of rotation of the pump rotor.
