摘要： A hydrojet for ships that navigate even in shallow waters has a pump wheel (3) that sucks water in the vertical direction and is provided with blades that let the water flow out of the pump wheel in a direction between vertical and horizontal. The water that leaves the flow channel of the pump wheel reaches a ring-shaped diffuser (5) without blades that guides the water pumped by the pump wheel into a pressure chamber (23), after deviating it by 160° to 200° (preferably 180°) in relation to the suction direction. The deviated water has only a low energy of flow and finally leaves the pressure chamber through nozzles (8) whose discharge direction is fixed or variable.
