| 摘要 |
The invention relates to an injector body for a fuel injection system, in which the injector body has a substantially cylindrically shaped valve chamber, into which fuel can be introduced at high pressure via an inlet bore, which discharges through an inlet opening in the valve chamber. To compensate for the high local notch tensile stresses in the circumferential direction of the valve chamber, it is proposed that at least in the region of the inlet opening, the valve chamber be provided with bulges, each adjacent the inlet opening in the circumferential direction. These bulges bring about a major compensation for the notch tensile stresses and thus increase the high-pressure strength.
