ELECTROMAGNETIC VALVE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; engines; remote control of fuel delivery in automobile gasoline pipe when automobile is furnished with antitheft device. SUBSTANCE: electromagnetic valve has additional winding connected in opposition with main winding and arranged so that both windings enclose the ends of core. Permanent magnet fixed by magnetic circuit locks in two extreme positions is used as core. Fixing is done for long time until electromagnetic valve is changed over by short - time application of polar voltage to opposite connected windings thanks to which like poles S-S or N-N are formed on magnetic locks. These poles act simultaneously onto core made of permanent magnet and its one end repels and the other, attracts. In process of changing over first repelling force prevails and at the end of process, attracting force. EFFECT: enlarged operating capabilities. 2 dwg
