ELECTROMAGNETIC CONTROL VALVE, IN PARTICULAR, FUEL INJECTOR Russian patent published in 2000 - IPC

FIELD: internal combustion engines. SUBSTANCE: device may be used for injection systems of internal combustion engines using compression of fuel mixture and forced ignition. Electromagnetic circuit, which comprises excitation coil, magnetic housing and core, which is designed as inner pole. Valve assembly, which serves as armature and locking body of valve, is designed as sphere and is mounted for axial movement inside magnetic housing. Resting member, which is located between core and valve assembly, has half-spherical resting surface, which is directed towards valve assembly. Valve assembly at least partially embraced by guiding body, which is also designed as half sphere, at least partially. EFFECT: increased efficiency of magnetic circuit, simplified design. 13 cl, 5 dwg
