ABSTRACT OF THE DISCLOSURE A hydraulic motor or pump constituted by an inner and outer helical year pair. The outer member of the pair is secured to one of the sections of at least one water swivel, and the inner member is connected to the other section by cooperting means associated with at least one end of said inner member and said other section, which prevent relative rotation while permitting relative gyration of said inner member with respect to said outer member. The stationary section of said swivel serves as a mounting means for the device. One or more gears, sprockets, pulleys or propellers may be secured to the rotating member of said pair, if it is the outer member which rotates, or to the rotating section of said swivel. By driving said rotating member,fluid may be pumped through the device, the direction of flow depending on the direction of rotation. By pumping fluid, by means of a separate pump,through said gear pair, the rotating member is caused to rotate in one direction or the other, depending on the direction of flow through said gear pair. With at least one propeller mounted on at least one rotating swivel section, or on the outer member if it is a rotating member, and driven by a separate pump, the device has utility for propulsion of a boat, barge, or semi-submersible well drilling platform, or for directional thrusting thereof, or with gears, sprockets or pulleys mounted on at least one rotating swivel section, it may simultaneously be used for driving auxiliary equipment. When the rotating member is driven by the use of gears, sprockets or pulleys, it may serve as a bilge pump.
