INDUCTION CYLINDRICAL PUMP Russian patent published in 2006 - IPC H02K44/06 H02K5/00 

FIELD: engineering of induction cylindrical pump, providing electromagnetic force effect on liquid-metallic heat carrier of working channel.

SUBSTANCE: pump has impermeable body with inducer positioned on it, containing winding and magnetic duct, compensation assembly, impermeable core, made of sheets of longitudinally-burdened electro-technical steel, acting as yoke for closing magnetic flow, distancing means and sliding support. Working channel is formed by thin-wall cowlings of impermeable inducer and internal core. Compensation assembly is made in form of corrugated tube insert.

EFFECT: compensation of various relative thermal expansions of body and external cowling of working channel, thus providing for impermeability of inducer.
