SOLENOID VALVE Russian patent published in 2004 - IPC

FIELD: valve engineering.

SUBSTANCE: solenoid valve comprises inlet and outlet bushings. Both of the bushings, cylindrical housing, and pipeline to be controlled are axially aligned. The control windings arranged on the bushings are connected in series and made of two units of the single control winding. The faces of the slide made of nonmagnetic material are provided with two radially magnetized permanent magnets. With a given polarity of the control current the magnetic flux of one of the units of the control winding is directed according to the magnetic flux of the permanent magnet adjacent to this unit. The magnetic flux of the second unit of the control winding points in opposite direction to that of the permanent magnet adjacent to it.

EFFECT: reduced mass and simplified mounting of the valve in pipeline.
