Abstract
Procedures introduced in a maritime drive device to facilitate forward and reverse propulsion, comprising a reversible hydraulic jet ejector structure arranged longitudinally within the hull of a maritime ship and arranged below the normal waterline so that the waters from the outside can pass from one narrow end of the drive to the other of said reversible ejection structure; said reversible ejector structure limited by the side walls of a longitudinal duct formed inside the hull structure of a maritime ship as mentioned; a pair of impulse-increasing secondary nozzle ejector phases, directed opposite each other, centrally arranged relative to said longitudinal duct, and each ejector phase arranged to discharge off the respectively adjacent drive end of said reversible ejector structure ; each ejector phase having a central drive nozzle arranged to supply high speed drive fluids into the center hole of at least one adjacent secondary nozzle member; each of said secondary nozzle members having a substantially frusto-conical shape and arranged in tandem relative to any other secondary nozzle member arranged adjacently such that the liquid discharge from one of said secondary nozzle members includes additional suction liquid the passage of the central liquid of said reversible ejector structure into the intake of a companion adjacent secondary nozzle member downstream; whereby the suction liquids can be reversibly accelerated both in one direction of propulsion and in the other, by the alternate supply of the pressurized driving liquids to the driving nozzles of said opposite nozzle ejector stages; a pressurized fluid source; and supply lines communicating between said source of pressurized driving fluid and each of said driving nozzles in the opposite directed secondary nozzle ejector stages; the total assembly comprises a reversible hydraulic jet ejector structure.
