ABSTRACT:
The present bow thruster for water vessels comprises a submersible axial flow pumping unit mounted on the outside of the vessel at the bow to be raised to an inoperative position out of the water or lowered to an operative position in the water with its water-flow axis perpendicular to the longitudinal centerline of the vessel. The pumping unit is reversible, and it includes a hydraulic motor and a pump impeller inside an annular housing provided with gate valves at its opposite ends. The gate valve at the discharge end restricts the flow there to increase the thrust produced by the pump. A directional control and a fluid pressure source for the hydraulic motor in the submersible pumping unit are on board the vessel.
