发明名称 Fuel injector valve
摘要 A fuel injection valve for injecting fuel includes: a coil, an internal pole, a valve sleeve, and a magnetic separating element, where the valve sleeve and the magnetic separating element are embodied in one piece as a powder injection-molded component, and the valve sleeve forms a magnetic region and the magnetic separating element forms a non-magnetic region, which are intermaterially joined to one another.
