Abstract
The invention provides sealing ring formed by a ring inner part and a bulge, the bulge extending radially outward at a right angle to a longitudinal axis of the ring so that a T-shaped cross section of the sealing ring is produced. The slightly conically extending inner surfaces of the sealing ring are pressed radially outward upon assembly so that a long guide area of the sealing ring on the contact pin is created which completely precludes any tilting of the sealing ring and increases the axial sealing. The sealing ring is particularly suitable for use in electromagnetically actuatable fuel injection valves.
