摘要： A propeller includes a hub having mounted on the central end part thereof a rotating fitting which permits the passage therethrough of a fluid circulating within two conduits which pass longitudinally of the fitting. The fluid operates on opposite ends of an annular piston to impart thereto rectilinear movement, which in turn is transformed into rotation of the blades of the propeller due to lugs extending from the piston and being eccentrically engaged with the blades. The hub of the propeller is completely free to turn without affecting the driving shaft. The assembly is positioned completely outside the stern of the ship.
