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. |

1. A fuel injection valve for injecting fuel, comprising:
a coil; an internal pole; a valve sleeve; and a magnetic separating element; wherein (i) the valve sleeve and the magnetic separating element are configured in one piece as a powder injection-molded component, (ii) the valve sleeve forms a magnetic region, (iii) the magnetic separating element forms a non-magnetic region, and (iv) the valve sleeve and the magnetic separating element are intermaterially joined to one another; wherein a welded join or soldered join is provided between the powder injection-molded component and the internal pole; wherein the internal pole has a pass-through opening in an axial direction; and wherein the internal pole is (i) configured as a powder injection-molded component and (ii) made of a material having a high magnetic saturation induction, including FeCo having a cobalt proportion from 17% to 50%. |
