FIELD: engines and pumps.

SUBSTANCE: invention relates to automotive industry, particularly, to diesel fuel preheaters. Proposed device comprises casing with inlet branch pipe with valve at one end and outlet branch pipe with valve and fine filter at opposite side. Said branch pipes are intercommunicated via bypass branch pipe. Said casing is shaped to cylinder to accommodate cylindrical magnetic core with inner slots filled with multiphase winding. Short-circuited cylindrical secondary is rigidly secured on magnetic core inner surface and composed of electrically conducting material. Said secondary accommodates cylindrical secondary composed of electrically conducting material to revolve therein. Pressure blades are rigidly engaged with inner surface of cylindrical secondary. Revolving cylindrical secondary and magnetic core are separated by self-lubing nonconducting material that doubles as radial thrust plain bearing.
