CYLINDRICAL LINEAR CONDUCTION PUMP Russian patent published in 2014 - IPC H02K44/04 

FIELD: electricity.

SUBSTANCE: cylindrical linear conduction pump comprises a shell and an inner cylindrical core, which create a circular channel. A flat insulation plate is placed in the circular channel and is tightly attached to a cylindrical core from a high-coercivity permanent magnet magnetised in an axial direction along its generatrix and a shell from ferromagnetic material. The cylindrical core and the inner surface of the shell have a chemically inert heat-resistant insulation plate, and the length of the plate meets the condition L_f>L_c+π·D_s-δ_f, where L_f - length of the flat plate, m, L_c - length of the cylindrical core, m, D_s - inner diameter of the shell, m, δ_f - thickness of the flat plate, m. At the ends of the flat plate in areas of poles of the cylindrical core at the opposite sides there are flat electrodes installed in pairs, the first pair of which is connected to appropriate outlets of the first adjustable source of DC voltage, and the second one - to appropriate outlets of the second adjustable source of DC voltage. Inlets of the first and second sources are connected to appropriate outlets of the setting unit.

EFFECT: reduced power costs and simplified adjustment of liquid flow.
