ELECTROMAGNETIC DOUBLE-ACTING DISPLACEMENT PUMP Russian patent published in 1994 - IPC

Abstract RU 2005911 C1

FIELD: manufacture of pumps. SUBSTANCE: pump housing embraced with solenoid coils is made of nonmagnetic material. Ferromagnetic piston mounted in housing forms two working chambers. Three coils mounted coaxially on housing are interconnected by star or delta manner and are connected to three-phase AC line. Noncontrolled diode is connected in series with each coil. Piston is assembled of flat plates made of magnetically soft material pressed in plastic. EFFECT: enhanced efficiency. 5 cl, 4 dwg
