FLUID TRANSFER DEVICE

Japanese Patent JP2022145462

A

To provide a fluid transfer device which applies a propulsive force to fluid.SOLUTION: A fluid transfer device comprises a magnet body forming a magnetic field with an annular-shaped cross section, and a cylindrical coil extending in a direction in which a cylindrical body extends in the magnetic field. The magnetic field is formed between a cylindrical stator part and a cylindrical rotor part extending in the direction in which the cylindrical body extends by sandwiching the coil between each other in a radial direction, and the magnet body is composed of a plurality of magnets which are arranged with a prescribed space between each other in a circumferential direction on a peripheral wall surface of the rotor part. Or the magnetic field is formed between a cylindrical outer yoke and a cylindrical inner yoke extending in the direction in which the cylindrical body extends by sandwiching the coil between each other in the radial direction, and the magnet body is composed of a plurality of magnets which are arranged with a prescribed space between each other in the circumferential direction on an inner peripheral wall surface of the outer yoke or an outer peripheral wall surface of the inner yoke, or both the inner peripheral wall surface of the outer yoke and the outer peripheral wall surface of the inner yoke. The plurality of magnets constituting the magnet body is rotated in the circumferential direction by energizing the coil, and a propulsive force is applied thereto.SELECTED DRAWING: Figure 1
