Title:
ANNULAR PASSAGE TYPE ELECTROMAGNETIC FLOW COUPLER
Document Type and Number:
Japanese Patent JPS6130954
Kind Code:
A
Abstract:
PURPOSE:To utilize a generated large current efficiency for the drive current of a pump by flowing the large current generated in a generator in a loop current coaxial with an annular passage. CONSTITUTION:An annular passage is formed between both inner and outer ducts 11 and 12 by disposing the cylindrical tubular inner duct 12 at the center of the cylindrical tubular outer duct 11, a partition plate 13 is provided substantially at the center of the passage to form the first and second passages 14, 15 in which different conductive fluids flow. A cylindrical outer magnet 15 is disposed on the outer periphery of the duct 11, and a rod-shaped core 17 of a magnetic material is inserted into the duct 12. When drive fluid 18 is fed to the passage 14, a loop current coaxial with the annular shape is generated, and the conductive fluid in the passage 15 is affected by the pumping operation by the current.
