Title:
MAGNETIC FLUID PUMP
Document Type and Number:
Japanese Patent JPS6096172
Kind Code:
A
Abstract:
PURPOSE:To obtain a pump which may not damage due to wear and tear and has excellent durability and reliability by circulating magnetic fluid by energizing an electromagnet and transporting the liquid by the pumping action of the magnetic fluid. CONSTITUTION:Magnetic fluids 3', 3'' in a tube 1 move in a direction of a branch port B of downstream side and liquid 10 is pumped and transported by the movement of the fluids, but when the fluids 3'' arrives at the port B, the energization of an electromagnet 4 is stopped, and an electromagnet 7 is, on the contrary, energized. Then, the fluid 3'' which is arrived at the port B is pushed into a bypass tube 2, and fluid 3 is, on the contrary, pushed out into the tube 1 newly from a branch port A of upstream side. Since the solvent of the fluid 3 is nonsoluble in the liquid 10, the fluid 3 is not dissolved in the liquid 10 nor mixed. Thus, mechanical slidable part can be eliminated to eliminate the possibility of damage due to wear and tear.
