ELECTROMAGNETIC INDUCTION PUMP-COMPRESSOR Russian patent published in 1996 - IPC

FIELD: pump-compressor engineering. SUBSTANCE: pump-compressor uses an annular casing composed of separate sections. Located inside each casing are cores with three-phase windings used to induce a travelling electromagnetic field in the form of a torus. An electromagnetic gate valve is installed between the inlet and outlet pipes. Shut-off electromagnet is a rectangular plate with a through hole. Electromagnet cores are rigidly secured at the ends of the rectangular plate. The through hole has a diameter larger than the piston diameter, it is shifted from the centre of the rectangular plate towards one of the electromagnet cores. EFFECT: improved design. 5 dwg
