Abstract
A fuel injection valve which serves to inject fuel into the intake tube of internal combustion engines. The fuel injection valve includes a valve housing, in which a nozzle body having a valve seat is firmly held. Downstream of the valve seat, the fuel is directed via metering fuel guide bores to a preparation bore, which is continued in the form of a preparation bore in an injection sheath. The injection sheath is held on the nozzle body by means of an adapter body surrounding and engaging the nozzle body, and it has an ejection segment within which the inside diameter of the preparation bore decreases in the flow direction toward the ejection end. Teeth are also provided on the ejection segment, pointing toward the ejection end.
