LIQUID PRESSURE MOTOR

Japanese Patent JPS51136051

A

A hydraulic motor or pump constituted by an inner and outer helical gear 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 cooperating elements associated with at least one end of the inner member and the other section, which prevent relative rotation while permitting relative gyration of the inner member with respect to said outer member. The stationary section of the swivel serves as a mounting for the device. One or more gears, sprockets, pulleys or propellers may be secured to the rotating member of the pair, if it is the outer member which rotates, or to the rotating section of the swivel. By driving the rotating member, fluid may be pumped through the device, the direction of flow depending on the direction of rotation. By pumping fluid, by a separate pump, through the gear pair, the rotating member is caused to rotate in one direction or the other, depending on the direction of flow through the 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.
